They rejected his statutes, and his covenant that he made with their fathers, and his testimonies which he testified to them; and they followed vanity, and became vain, and [ergänzt: went] after the nations that were round about them, concerning whom Yahweh had charged those who they should not do like them.

וַיֶּהְבָּ֔לוּ (יֶּהְבָּ֔לוּ) i.yeh.Ba.lu “they became vain”

Behold, all of you have seen it yourselves; Why then have you become altogether vain?

תֶּהְבָּֽלוּ׃ teh.Ba.lu “do you act in vain”

Don't trust in oppression. Don't become vain in robbery. If riches increase, Don't set your heart on them.

תֶּ֫הְבָּ֥לוּ teh.Ba.lu “you put vain hope”

thus says Yahweh, What unrighteousness have your fathers found in me, that they have gone far from me, and have walked after vanity, and are become vain?

וַיֶּהְבָּֽלוּ׃ (יֶּהְבָּֽלוּ) i.yeh.Ba.lu “they became vain”

Thus says Yahweh of Hosts, Don't listen to the words of the prophets who prophesy to you: they teach you vanity; they speak a vision of their own heart, and not out of the mouth of Yahweh.
