Matthew Poole and continuators on Jeremiah 10:16

16 The portion of Jacob is not like them, for he is the former of all things, and Israel is the rod of his inheritance, the LORD of hosts is his name.

A Periphrasis for the true God, who vouchsafeth to be the portion of his People and to be so called, Deut. 32.9. Psal. 16.5. and many other places because he is in Covenant with his people in the Messiah, whose co-heirs are as dear to him as a portion is, that descends to a man by inheritance, and he tells you his Name in the close of the verse, Isa. 47.44. one who hath the whole Host of Heaven and Earth at his disposal.

Idols are things framed and formed, but God is the former of all things, the maker of heaven and earth.

So called, because the portions and inheritances of Israel were measured by a line, reed, or rod, and therefore called the rod of his Inheritance, Deut. 32.8, 9. Psal. 74.2. and because they were his by a continual line of Succession; beside Israel is, [non-Latin text not transcribed] Schebet the Rod, or Scepter of his Inheritance, because God did set up his Kingdom in Israel.
