Isaiah 27:1-2

Amplified Bible, Classic Edition

27 In that day [the Lord will deliver Israel from her enemies and also from the rebel powers of evil and darkness] His sharp and unrelenting, great, and strong sword will visit and punish Leviathan the swiftly fleeing serpent, Leviathan the twisting and winding serpent; and He will slay the monster that is in the sea.

² In that day [it will be said of the redeemed nation of Israel], A vineyard beloved and lovely; sing a responsive song to it and about it!
