'According to the Word of the Lord' in the Bible

So Ahaziah [the son of King Ahab] died in accordance with the word of the Lord which Elijah had spoken. And because he had no son, Jehoram [his younger brother] became king [of Israel, the northern kingdom] in his place in the second year of Jehoram the son of Jehoshaphat, king of Judah [the southern kingdom].

Jeroboam restored Israel’s border from the entrance of Hamath to the Sea of the Arabah (Dead Sea), in accordance with the word of the Lord, the God of Israel, which He spoke through His servant Jonah the son of Amittai, the prophet who was from Gath-hepher.

The Lord sent marauding bands of Chaldeans, Arameans (Syrians), Moabites, and Ammonites against Jehoiakim. And He sent them against Judah to destroy it, in accordance with the word of the Lord which He spoke through His servants the prophets.
