Jeremiah 35:18-19

35:18 Then Jeremiah spoke to the Rechabite community, “The Lord God of Israel who rules over all says, ‘You have obeyed the orders of your ancestor Jonadab. You have followed all his instructions. You have done exactly as he commanded you.’ 35:19 So the Lord God of Israel who rules over all says, ‘Jonadab son of Rechab will never lack a male descendant to serve me.’”
