John Gill Commentary Jeremiah 35:5

"And I set before the sons of the house of the Rechabites bowls full of wine, and cups; and I said unto them, Drink ye wine." — Jeremiah 35:5 (ASV)

And I set before the sons of the house of the Rechabites pots
full of wine, and cups
Which the prophet might have out of the chambers where these vessels were, and particularly from Maaseiah, if he was a keeper of them, as before observed. The number of men gathered together was probably very large; and therefore pots, or large vessels of wine, were prepared, and set before them, and cups, lesser vessels, to drink out of.

and I said to them, drink you wine ;
he invited them to it, and bid them welcome; nay, more, he might not only encourage, but enjoin them to drink it; though, as Gataker observes, he does not say to them, "thus saith the Lord, drink wine"; for then they must have done it, and doubtless would; since it is right to obey God rather than man, even parents.
