Matthew Poole and continuators on Jeremiah 17:2

2 Whilest their children remember their altars, and their groves, by the green trees, upon the high hills .

This shewed how inveterate they were in this sin of Idolatry, that they taught it their Children, and their Children remembred their idolatrous Altars, and the Groves, where they were wont to worship Idols by the green Trees, as they did also upon the High Hills, so their sin was derived from one age to another. Others think that the phrase rather expresseth their fondness of their Idols, and think it should be read, as their Children, they remember, &c. that is they loved their Idols, and their Idolatrous services, as they loved their Children, which also was true, yea they that made their Children pass through the fire to Molech, loved them better then their Children.
