Psalm 95/Notes/Verbal.V. 7c.726226
For the modality of agent-oriented desire in the protasis of the conditional, see Khan (forthcoming, "Yiqṭol," 147; cf. IBHS §31.4h), in which case the protasis and apodosis often contain similar semantics, so there is no tautology involved. For similar examples, cf. "But if you want to make a burnt sacrifice to the Lord, you should offer it" (Judg 13:16, NET); "If you want to take it for yourself, then take it" (1 Sam 21:10, CSB); "If you want to ask, ask" (Isa 21:12, NET); "Israel, if you want to come back, then come back to me" (Jer 4:1, ERV); "if he wants to do his duty as your guardian-redeemer, good; let him redeem you" (Ruth 3:13, NIV); "If you want to exercise your right to redeem it, then do so" (Ruth 4:4, NET).
