Matthew Poole and continuators on Jeremiah 2:16

16 Also the children of Noph and Tahapanes have broken the crown of thy head.

They that take the Heb. word in the notion of breaking, understand this of destroying what ever is chief, or principal among them, either of persons, or things wounds in the head being most dangerous. Or, defiling the chief of the Land, either by their corporal Adulteries, and so take the word under the notion of knowing as Gen. 19.5. or spiritual, namely Idolatries, chap. 44.17. or their cruel Tyrannical oppressions, trampling upon all their glory expressed by riding over their heads, and that universally in a most insulting manner, but the word may be better taken in the notion of feeding, as the word is used, chap. 3.15. i. e. They have fed upon her most fruitful, and pleasant, the top and head of all her Pastures, that lay in the Southern Borders towards Egypt, see chap. 13.18, 19, 20. thus depriving them of all way of subsistance, chap. 12.10. In short they shall make havock of all, that is excellent in thee, Isa. 28.4. the sum is, thy league O Iudea with Egypt against the Chaldeans will be the cause of thy total ruin. For the Kings of Iudah had not rebelled against the Babylonians, but to gratifie the Egyptians in expectation of help from them.

Two of the King of Egypt's principal seats concerning Noph sometimes called Memphis, now Cayro, See on Isa. 19.13. Concerning Tahapanes, see Ezek. 30.18. probably talking its name from Tahpenes Queen of Egypt, 1 Kings 11.19. called also Hanes, see on Isa. 30.4. and the Inhabitants, and Natives of these Cities are called here their Children, Isa. 37.12.
