[51:11] 1 tn Heb “do not cast me away from before you.”
[51:11] 2 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.”
[51:11] 3 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).
[51:12] 4 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.
[51:13] 7 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.
[51:13] 8 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).
