Jeremias 7:8 Meaning and Commentary

Jeremiah 7:8

Behold, ye trust in lying words
What they are dissuaded from, ( Jeremiah 7:4 ) , is here affirmed they did, and which is introduced with a note of asseveration, attention, and admiration; it being a certain thing that they did so; and was what was worthy of their consideration and serious reflection upon; and it was astonishing that they should, since so to do was of no advantage to them, but the contrary: that cannot profit;
temple worship and service, legal sacrifices and ceremonies, could not take away sin, and expiate the guilt of it; or justify men, and render them acceptable to God; these, without faith in the blood and sacrifice of Christ, were of no avail; and especially could never be thought to be of any use and profit, when such gross abominations were indulged by them as are next mentioned.

Jeremias 7:8 In-Context

6 and oppress not the stranger, and the orphan, and the widow, and shed not innocent blood in this place, and go not after strange gods to your hurt:
7 then will I cause you to dwell in this place, in the land which I gave to your fathers of old and for ever.
8 But whereas ye have trusted in lying words, whereby ye shall not be profited;
9 and ye murder, and commit adultery, and steal, and swear falsely, and burn incense to Baal, and are gone after strange gods whom ye know not,
10 so that it is evil with you; yet have ye come, and stood before me in the house, whereon my name is called, and ye have said, We have refrained from doing all these abominations.
