Jeremias 16:12 Meaning and Commentary

Jeremiah 16:12

And ye have done worse than your fathers
Not only committed the same sins, but greater, or, however, attended with more aggravating circumstances; they were wilfully and impudently done, and obstinately persisted in; and therefore deserving of the great evil of punishment pronounced against them.

to the word of the Lord, and obey that; their minds being blinded, and their hearts hardened, and they obstinately bent on their own evil ways.

12 (and ye sinned worse than your fathers; for, behold, ye walk every one after the lusts of your own evil heart, so as not to hearken to me);
13 therefore I will cast you off from this good land into a land which neither ye nor your fathers have known; and ye shall serve their other gods, who shall have no mercy upon you.
14 Therefore, behold, the days come, saith the Lord, when they shall no more say, The Lord lives, that brought up the children of Israel out of the land of Egypt;
