All that's left…

Like so often in the psalms, David entrusts himself to Yhwh’s mercy (cf. Ps 51:1 [MT 51:3]). Divine mercy is one of the fundamental attributes that Yhwh has revealed to Moses in the aftermath of Israel’s archetypal sin, the golden calf (רחם [rḥm]; cf. Exod 34:6). Since then, Israel has invoked divine mercy, as one of the last resorts, like one who has nothing left to claim for oneself, but to throw oneself to the “womb pity” of God (רחם [rḥm]; cf. Dan 9:18).—Standing in the Breach, page 237
