[51:14] 1 tn Heb “from bloodshed.” “Bloodshed” here stands by metonymy for the guilt which it produces.
[51:14] 2 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).
[51:15] 3 tn Heb “open my lips.” The imperfect verbal form is used here to express the psalmist’s wish or request.
