While we read in this account how Jehu waded through blood, I pray the reader to keep in view that he acted as the instrument of the Lord. The commission was from heaven. And when we take into the account how Ahab by his idolatry had been ruining the souls as well as the bodies of Israel, surely such daring impiety called for more than ordinary vengeance!
2 Kings 10:8-11
8 And there came a messenger, and told him, saying, They have brought the heads of the king's sons. And he said, Lay ye them in two heaps at the entering in of the gate until the morning.
9 And it came to pass in the morning, that he went out, and stood, and said to all the people, Ye be righteous: behold, I conspired against my master, and slew him: but who slew all these?
10 Know now that there shall fall unto the earth nothing of the word of the LORD, which the LORD spake concerning the house of Ahab: for the LORD hath done that which he spake byb his servant Elijah.
11 So Jehu slew all that remained of the house of Ahab in Jezreel, and all his great men, and his kinsfolks,c and his priests, until he left him none remaining.
