Coolant is one of the most important fluids in a vehicle, yet it is often overlooked because drivers rarely see it in action. Circulating through the engine and radiator, coolant absorbs excess heat generated during combustion and carries it away before temperatures reach damaging levels. Without an effective cooling system, an engine can overheat within minutes, leading to warped components, blown head gaskets, or even complete engine failure. Modern coolant formulations also help prevent corrosion, lubricate water pumps, and protect the system from freezing in cold weather.

What makes coolant particularly interesting is that its importance often goes unnoticed until there is a problem. Drivers may admire a vehicle’s horsepower, styling, or technology, but few think about the fluid quietly flowing through hoses and passages beneath the hood. Yet even the most powerful engine cannot function for long without a steady supply of coolant. It is one of those essential systems that operates behind the scenes, sustaining performance and reliability while receiving little attention when everything is working as it should.

The importance of coolant offers an interesting parallel to the role of water in the Torah reading of Chukat in the Book of Numbers. Just as a vehicle can travel countless miles without its driver giving much thought to the cooling system, the Israelites benefited for decades from a reliable source of water in the wilderness. According to Jewish tradition, the well that accompanied the nation existed in Miriam’s merit, and its disappearance following her death suddenly revealed how essential it had been all along. What had quietly sustained the people for years was now gone, and a crisis quickly unfolded. Faced with thirst and fear, the nation gathered against Moses and Aaron, lamenting their situation and demanding water. In the midst of the tension, Moses stood before the rock, and after striking it, water burst forth in abundance, enough to satisfy the entire community and their livestock. Like a failed cooling system that suddenly brings a journey to a halt, the loss of water transformed an unseen necessity into the central drama of the moment. And just as restoring coolant allows an engine to continue down the road, the renewed flow of water enabled Israel to continue its long journey toward the Promised Land.

Reviewing the reading of Chukat in the Book of Numbers (Chapters 19-22), we are introduced to the particularly unusual laws of the red heifer, which provide ritual purification from contact with the dead. These laws only applied in the times of the Tabernacle and the Temple, though there are a number of groups today that have been raising pure red cows.

The Torah tells us how a completely red cow without blemish is brought outside the camp and slaughtered. Its blood is sprinkled, and the entire animal is burned together with cedar wood, hyssop, and crimson material. The ashes are collected and stored for use in purification.

Anyone who comes into contact with a dead body becomes impure for seven days. Water mixed with the ashes is sprinkled on the third and seventh days to restore purity. Various laws are given concerning impurity from death, including tents containing a corpse and objects found within them.

The Israelites arrive at the wilderness of Zin and camp at Kadesh. Miriam dies there and is buried.

The people have no water and gather against Moses and Aaron. They complain about being brought into the wilderness and long for the conditions they remember from Egypt.

Moses and Aaron go to the Tent of Meeting, where instructions are given to speak to a rock before the people so that it will provide water. Moses gathers the people before the rock and speaks angrily to them. He then strikes the rock twice with his staff. Water pours out, and the people and their livestock drink.

Because Moses and Aaron did not sanctify God before the people in this event, they are told that they will not bring the nation into the promised land. The issue of how exactly they didn’t “sanctify God” is the discussion of more than a dozen different commentaries, each with their own opinion of what the fault was.

Messengers are sent to the king of Edom requesting passage through his territory. Israel promises not to use the fields, vineyards, or wells and to remain on the main road. Edom refuses and comes out with a large force. Israel turns away.

The people travel to Mount Hor. Aaron is told that he will die there and not enter the land. Moses, Aaron, and Eleazar ascend the mountain. Aaron’s priestly garments are removed and placed on Eleazar. Aaron dies on the mountain, and Moses and Eleazar descend. The entire nation mourns Aaron for thirty days.

The Canaanite king of Arad hears of Israel’s approach and attacks. An Israelite is taken captive. Israel vows that if victory is granted, the cities will be destroyed. The Canaanites are defeated, and their cities are destroyed.

The people continue traveling and become impatient. They complain against God and Moses, criticizing the manna and the journey. Venomous snakes appear among the people, and many die.

The people admit their wrongdoing and ask Moses to pray for them. Moses does so. He makes a bronze serpent and places it on a pole. Those who have been bitten look at it and live. (Perhaps the ancient source for the physician’s symbol of the snakes around a pole?)

Israel travels through a series of wilderness locations and camps near the border of Moab. Songs are sung celebrating a well that provided water.

Messengers are sent to Sihon, king of the Amorites, requesting passage through his land. He refuses and attacks. Israel defeats him and captures his cities, taking possession of the territory.

They then advance toward Bashan, whose king is Og. Og is a giant and it states that Moses was fearful. God tells him not to fear. Og comes out to battle with his people. Israel defeats him as well and takes his land.

The portion concludes with Israel encamped in the plains of Moab, across the Jordan River from Jericho, preparing for the next stage of the journey.

While there is much more material (we still have a Book and half left), this is the final encampment after close to 40 years of wandering in the desert. We will have some more events that occur at the plains of Moab before the death of Moses and the closing of his Five Books.

Next week we have the unusual story of Balak, king of Moab, who attempts to curse the people of Israel through the sorcerer Bilaam. It’s a wild story, featuring a talking donkey (Shrek was not the first to think of that…)
