Psalm 4/Notes/Summary.v. 4.846347

David points to recent history as grounds for worshipping YHWH instead of other gods: “Know that YHWH has set apart,” or treated in an excellent way, “one who is loyal to him; YHWH hears when I call out to him.” When David called out, YHWH was not stingy in response; he set David apart in the sense of singling him out for excellent treatment. In this recent time of drought and famine, God singled out Israel, in the form of their king, David, and protected them from famine: he brought rain that led to abundant harvests.
