¹ sn Psalm 51. The psalmist confesses his sinfulness to God and begs for forgiveness and a transformation of his inner character. According to the psalm superscription, David offered this prayer when Nathan confronted him with his sin following the king’s affair with Bathsheba (see 2 Sam 11-12). However, the final two verses of the psalm hardly fit this situation, for they assume the walls of Jerusalem have been destroyed and that the sacrificial system has been temporarily suspended. These verses are probably an addition to the psalm made during the period of exile following the fall of Jerusalem in 586 b.c. The exiles could relate to David’s experience, for they, like him, and had been forced to confront their sin. They appropriated David’s ancient prayer and applied it to their own circumstances.

² tn Heb “a psalm by David, when Nathan the prophet came to him when he had gone to Bathsheba.”

³ tn Or “according to.”

⁴ tn Or “according to.”

⁵ tn Traditionally “blot out my transgressions.” Because of the reference to washing and cleansing in the following verse, it is likely that the psalmist is comparing forgiveness to wiping an object clean (note the use of the verb מָחָה (makhah) in the sense of “wipe clean; dry” in 2 Kgs 21:13; Prov 30:20; Isa 25:8). Another option is that the psalmist is comparing forgiveness to erasing or blotting out names from a register (see Exod 32:32-33). In this case one might translate, “erase all record of my rebellious acts.”

⁶ tn Heb “Thoroughly wash me from my wrongdoing.”

⁷ sn In vv. 1b-2 the psalmist uses three different words to emphasize the multifaceted character and degree of his sin. Whatever one wants to call it (“rebellious acts,” “wrongdoing,” “sin”), he has done it and stands morally polluted in God’s sight. The same three words appear in Exod 34:7, which emphasizes that God is willing to forgive sin in all of its many dimensions. In v. 2 the psalmist compares forgiveness and restoration to physical cleansing. Perhaps he likens spiritual cleansing to the purification rites of priestly law.

⁸ sn The heart is viewed here as the seat of the psalmist’s motives and moral character.

⁹ tn Heb “and a reliable spirit renew in my inner being.”

¹⁰ tn Heb “do not cast me away from before you.”

¹¹ sn Your Holy Spirit. The personal Spirit of God is mentioned frequently in the OT, but only here and in Isa 63:10-11 is he called “your/his Holy Spirit.”

¹² sn Do not take…away. The psalmist expresses his fear that, due to his sin, God will take away the Holy Spirit from him. NT believers enjoy the permanent gift of the Holy Spirit and need not make such a request nor fear such a consequence. However, in the OT God’s Spirit empowered certain individuals for special tasks and only temporarily resided in them. For example, when God rejected Saul as king and chose David to replace him, the divine Spirit left Saul and came upon David (1 Sam 16:13-14).

¹³ 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.

¹⁴ tn The cohortative expresses the psalmist’s resolve. This may be a vow or promise. If forgiven, the psalmist will “repay” the Lord by declaring God’s mercy and motivating other sinners to repent.

¹⁵ tn Heb “your ways.” The word “merciful” is added for clarification. God’s “ways” are sometimes his commands, but in this context, where the teaching of God’s ways motivates repentance (see the next line), it is more likely that God’s merciful and compassionate way of dealing with sinners is in view. Thanksgiving songs praising God for his deliverance typically focus on these divine attributes (see Pss 34, 41, 116, 138).

¹⁶ tn Or “return,” i.e., in repentance.

¹⁷ tn Heb “from bloodshed.” “Bloodshed” here stands by metonymy for the guilt which it produces.

¹⁸ 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).
