If there be in the land famine, if there be pestilence, blasting, mildew, locust, or if there be caterpiller; if their enemy besiege them in the land of their cities; whatsoever plague, whatsoever sickness there be;

If thy people go out to battle against their enemy, whithersoever thou shalt send them, and shall pray unto the LORD toward the city which thou hast chosen, and toward the house that I have built for thy name:

If they sin against thee, (for there is no man that sinneth not,) and thou be angry with them, and deliver them to the enemy, so that they carry them away captives unto the land of the enemy, far or near;

So the Lord raised up Hadad the Edomite as an enemy against Solomon. He was of the royal family in Edom.

God raised up Rezon son of Eliada as an enemy against Solomon. Rezon had fled from his master Hadadezer king of Zobah

Rezon was Israel’s enemy throughout Solomon’s reign, adding to the trouble Hadad had caused. He ruled over Aram, but he loathed Israel.

Each one struck down an enemy soldier; the Syrians fled and Israel chased them. King Ben Hadad of Syria escaped on horseback with some horsemen.

And Ahab said to Elijah, Hast thou found me, O mine enemy? And he answered, I have found thee: because thou hast sold thyself to work evil in the sight of the LORD.
