Matthew Poole and continuators on Jeremiah 9:26

26 Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that are in the utmost corners, that dwell in the wilderness: for all these nations are uncircumcised, and all the house of Israel are uncircumcised in the heart.

Some refer this to the place of their habitation, as in corners, and remote parts of the wilderness, as it were separated from other Nations, and therefore might think themselves farthest remote from danger, but some rather chuse to refer it to their manners, as in cutting the corners of their hair, which was forbidden the Iews, Lev. 19.27. The like description in chap. 25.23.

See the foregoing verse, God regards not the outward sign, but principally respects the circumcision of the heart, here ends that Sermon that began at chap. 7.

Marginal references: Heb. cut off into corners, or having the corner of their hair p[illegible: 1 letter]lled.; Lev. 26.41. Rom. 2.28, 29.
