Isaiah 27

In that day, YHWH will slay **Leviathan** the fleeing and twisting serpent, the dragon in the sea; He tends His **pleasant vineyard** (Israel), guarding it from briers and thorns, promising that Jacob will take root, blossom, and fill the world with fruit[1][3][4]. Jacob’s guilt is atoned by destroying pagan altars and Asherah poles, the fortified city becomes desolate for a people without understanding, and YHWH will gather Israel one by one from the river to Egypt for worship in Jerusalem[1][2][5].
