'Destroyer' in the Bible

And do not murmur [in unwarranted discontent], as some of them did—and were destroyed by the destroyer.

By faith he kept the Passover and the sprinkling of the blood [on the doorposts], so that the destroyer of the firstborn would not touch them (the firstborn of Israel).

They have as king over them, the angel of the abyss (the bottomless pit); in Hebrew his name is Abaddon (destruction), and in Greek he is called Apollyon (destroyer-king).
