'Angel' in the Bible

either three years of famine; or three months to be consumed before thy foes, while the sword of thine enemies overtaketh thee; or else three days the sword of Jehovah, even pestilence in the land, and the angel of Jehovah destroying throughout all the borders of Israel. Now therefore consider what answer I shall return to him that sent me.

And God sent an angel unto Jerusalem to destroy it: and as he was about to destroy, Jehovah beheld, and he repented him of the evil, and said to the destroying angel, It is enough; now stay thy hand. And the angel of Jehovah was standing by the threshing-floor of Ornan the Jebusite.

And David lifted up his eyes, and saw the angel of Jehovah standing between earth and heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, clothed in sackcloth, fell upon their faces.

Then the angel of Jehovah commanded Gad to say to David, that David should go up, and rear an altar unto Jehovah in the threshing-floor of Ornan the Jebusite.

And Ornan turned back, and saw the angel; and his four sons that were with him hid themselves. Now Ornan was threshing wheat.

And Jehovah commanded the angel; and he put up his sword again into the sheath thereof.

But David could not go before it to inquire of God; for he was afraid because of the sword of the angel of Jehovah.
