Do good to Zion in your good pleasure;
rebuild the walls of Jerusalem,
then you will delight in right sacrifices,
in burnt offerings and whole burnt offerings;
then bulls will be offered on your altar.
Psalm 51:18–19, NRSV
This reference clearly identifies the psalm, at least in its final form, as a post-exilic work. Psalms with a theme of penitence are increasingly thought to have their origin in the post-exilic period. The seven penitential psalms all have a concerns beyond the penitent prayer’s context. This can be the psalmist’s enemies, the nations, the people of God and/or Zion.
Psalm 102 also refers to the City of Peace. In fact, it’s a central concern from verse 12 through to verse 22. Something I have noticed is that each of the penitential psalms can be read as prayer on behalf of the post-exilic people of God, rather than through a Davidic or personal lens. The legitimacy of such a interpretive lens will be something I will explore at some future point.
The reference to Zion in Psalm 51 brings back the theme of sacrifices mentioned in the preceding two verses:
For you have no delight in sacrifice;
if I were to give a burnt offering, you would not be pleased.
The sacrifice acceptable to God is a broken spirit;
a broken and contrite heart, O God, you will not despise.
Psalm 51:16–17, NRSV
At first sight the two references to sacrifice seem entirely contradictory and indeed are likely the result of editing. The claim that Yahweh would not delight in sacrifice (v.16) coheres with the penitential nature of Psalm 51 and its emphasis that God’s mercy can be sought if one is truly penitent, that is contrite (v.17). Perhaps the later editor, or even the original psalmist, whilst celebrating this remarkable truth acknowledges nevertheless that they still live in the midst of a religious cultus where ‘right sacrifices’ are formally required. Another aspect that heals the apparent rift between the two claims is that in vv.16-17 the concern is arguably a polar comparison between a mechanical sacrifice, and genuine contrition and petition. Under the Law the best outcome is still right sacrifice, i.e. a physical offering arising from heartfelt contrition.
The beauty of this psalm today is that in Christ we can call on God’s mercy, with the knowledge that through the cross we can reread this psalm and know the promise of his mercy through water, wine and bread.
