Matthew Poole and continuators on Joshua 24:2

2 And Joshua said unto all the people , Thus saith the LORD God of Israel, your fathers dwelt on the other side of the floud in old time, even Tera the father of Abraham, and the father of Nachor: and they served other gods.

i. e. That people which were present, to wit, to the Elders, &c. by whom it was to be imparted to all the rest, and to as many of the people as came thither.

Or, the River, to wit, Euphrates, as all agree, so called by way of Eminency.

i. e. Both Abraham and Nahor were no less Idolaters than the rest of Mankind. This is said to prevent their vain boasting in their worthy Ancestors, and to assure them that whatsoever good was in, or had been done by their Progenitors, was wholly from Gods free Grace, and not for their own merit or righteousness, as the Iews were very apt to conceit.

Marginal references: Gen. 11. 26, 31. and 12. 1.; Heb. Meolam, that is, from everlasting.
