Thus saith the LORD unto this people, Thus have they loved to wander, they have not refrained their feet, therefore the LORD doth not accept them; he will now remember their iniquity, and visit their sins.
Thus saith the Lord - Yahweh's reply to the prayer (Jeremiah 14:7-9; Jeremiah 2:23-25).
Thus - So greatly.
Loved - (Jeremiah 5:31, "My people love to have it so").
Not refrained their feet - they did not obey God's command, "Withhold thy foot" (Jeremiah 2:25) - namely, from following after idols.
He will now remember their iniquity - (Hosea 8:13; Hosea 9:9). Their sin is so great God must punish them.
