'Vent' in the Bible

“I loathe my own life;I will give full vent to my complaint;I will speak in the bitterness of my soul.

"It will come about that, when he has filled himself to the full, God will vent his burning anger on him; he will pour it out on him and on his body.

Behold, my belly is as wine which hath no vent; it is ready to burst like new bottles.
