Among the biblical texts that underlie the psalm is Isaiah 11, the description of the future king of the line of David. The messiah in Psalms of Solomon 17 will be endowed with wisdom and strength (Isaiah 11:2), and he will destroy the unlawful “with the word of his mouth” (Isaiah 11:4). Another scriptural proof text from the Old Testament is Psalm 2, whose king will be victorious over the rulers of the nations.
