'Enemy' in the Bible

Blow the horn in Gibeah,The trumpet in Ramah [the lofty hills on Benjamin’s northern border].Sound the alarm at Beth-aven:“Behind you and coming after you [is the enemy], O Benjamin [be on guard]!”

Set the trumpet to your lips [announcing impending judgment]!Like a [great] vulture the enemy comes against the house of the Lord,Because they have broken My covenantAnd transgressed and rebelled against My law.

Israel has rejected the good;The enemy shall pursue him.
