Mazmur 51:12

51:12 Let me again experience the joy of your deliverance!

Sustain me by giving me the desire to obey! ¹ 

Mazmur 51:14

51:14 Rescue me from the guilt of murder, ²  O God, the God who delivers me!

Then my tongue will shout for joy because of your deliverance. ³ 

[51:12]  ¹ tn Heb “and [with] a willing spirit sustain me.” The psalmist asks that God make him the kind of person who willingly obeys the divine commandments. The imperfect verbal form is used here to express the psalmist’s wish or request.

[51:14]  ² tn Heb “from bloodshed.” “Bloodshed” here stands by metonymy for the guilt which it produces.

[51:14]  ³ tn Heb “my tongue will shout for joy your deliverance.” Another option is to take the prefixed verbal form as a jussive, “may my tongue shout for joy.” However, the pattern in vv. 12-15 appears to be prayer/request (see vv. 12, 14a, 15a) followed by promise/vow (see vv. 13, 14b, 15b).
