John Calvin's Bible Commentary
Jeremiah 7:29
Here again Jeremiah exhorts his own people to lament; and he uses the feminine gender, as though he called the people, the daughter of Sion, or the daughter of Jerusalem. He then, according to a common mode of speaking, calls the whole people a woman. (211)
He first bids her to shave off the hair The word נזר, nesar, means the hair, derived from the Nazarites, who allowed their hair to grow: and there may be here a striking allusion to the Nazarites who were sacred to God; as though he had said, “This people are profane, and therefore ought to have nothing in common with the Nazarites.” Hence also is derived נזר, nesar, a crown.

It is indeed true, that the Israelites in every age were worthy of a similar vengeance; but God no doubt shews here, that his vengeance was at hand, for he had long borne with the perverse conduct of the people, and suspended his judgment. As then vengeance was now to be executed, the Prophet calls that age the age of God’s wrath; for we know that the genitive case in Hebrew has often such a meaning as this. Then the age of his wrath means the age or generation devoted to extreme vengeance; for their wickedness against God was extreme, as long as he treated them with forbearance. The longer then he had deferred his judgment, the heavier punishment was at hand. It afterwards follows —
