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

So all the elders of Israel came to the king at Hebron, and David made a covenant (solemn agreement) with them there before the Lord; and they anointed him king over Israel, in accordance with the word of the Lord through Samuel.

Now these are the chiefs of David’s mighty men, who strongly supported him in his kingdom, together with all Israel, to make him king, in accordance with the word of the Lord concerning Israel.

These are the numbers of the [armed] units equipped for war who came to David at Hebron to turn [over] the kingdom of Saul to him, in accordance with the word of the Lord.
