Job 40:4

And they said to him, “Be silent; put your hand over your mouth and come with us and be to us a father and a priest. Is it better for you to be a priest to the house of one man or to be priest to a tribe and a family in Israel?”

“Look at me, and be appalled, And put your hand over your mouth.

Now it happened after Yahweh had spoken these words to Job, that Yahweh said to Eliphaz the Temanite, “My anger burns against you and against your two friends because you have not spoken of Me what is right as My servant Job has.

If you have been wickedly foolish in lifting yourself up, Or if you have schemed evil, put your hand on your mouth.

Let him put his mouth in the dust; Perhaps there is hope.
