1 tn Grk “before your face” (an idiom).
2 sn The quotation is primarily from Mal 3:1 with pronouns from Exod 23:20. Here is the forerunner who points the way to the arrival of God’s salvation. His job is to prepare and guide the people, as the cloud did for Israel in the desert.
3 tn Grk “sending on you.”
4 tn Grk “the promise of my Father,” with τοῦ πατρός (tou patros) translated as a subjective genitive. This is a reference to the Holy Spirit and looks back to how one could see Messiah had come with the promise of old (Luke 3:15-18). The promise is rooted in Jer 31:31 and Ezek 36:26.
5 sn The city refers to Jerusalem.
6 sn Until you have been clothed with power refers to the coming of the Holy Spirit at Pentecost. What the Spirit supplies is enablement. See Luke 12:11-12; 21:12-15. The difference the Spirit makes can be seen in Peter (compare Luke 22:54-62 with Acts 2:14-41).
