Acts 2:4

“And they were all filled with the Holy Ghost, etc.] With the gifts of the Holy Spirit; they had received the Spirit before, as a Spirit of grace, and were endowed with great gifts; but now they had great plenty of them, a large abundance; they were like vessels filled to the brim; they were as it were covered with them; there was an overflow of them upon them; and now it was, that they were baptized with him; (See Gill on “<440105>Acts 1:5”). Not only the twelve apostles, but the seventy disciples; and it may be all the hundred and twenty, that were together, even women as well as men: (<440217>Acts 2:17,18). And began to speak with other tongues; besides, and different from that in which…”

“they . . . began to speak with . . . tongues, &c.--real, living languages, as is plain from what follows. The thing uttered, probably the same by all, was "the wonderful works of God," perhaps in the inspired words of the Old Testament evangelical hymns; though it is next to certain that the speakers themselves understood nothing of what they uttered (see on 1Co. 14:1-25).”

“Were all filled with the Holy Ghost - Were entirely under his sacred influence and power. See the notes on Luke 1:41, Luke 1:67. To be filled with anything is a phrase denoting that all the faculties are pervaded by it, engaged in it, or under its influence, Acts 3:10, “Were filled with wonder and amazement”; Acts 5:17, “Filled with indignation”; Acts 13:45, “Filled with envy”; Acts 2:4, “Filled with joy and the Holy Spirit.” Began to speak with other tongues - In other languages than their native tongue. The languages which they spoke are specified in Acts 2:9-11. As the Spirit gave them utterance - As the Holy Spirit gave them power to speak. This language implies plainly that they were…”

“And they began to speak with other tongues - The miracle was not in the ears of the hearers, (as some have unaccountably supposed,) but in the mouth of the speakers. And this family praising God together, with the tongues of all the world, was an earnest that the whole world should in due time praise God in their various tongues. As the Spirit gave them utterance - Moses, the type of the law, was of a slow tongue; but the Gospel speaks with a fiery and flaming one. Acts 2:5”

“2:4 everyone present was filled with the Holy Spirit: This event marks the coming of the Holy Spirit to fill Jesus’ disciples, as he had promised, so that they could be powerful witnesses (1:4-5, 8). The Spirit’s wisdom, energy, and power were the driving force behind the church’s work and witness (e.g., 2:14-41, 43; 4:31; 9:17, 20; 13:9-12; see also Eph 5:18). • began speaking in other languages: The Holy Spirit gave extraordinary communication that made it possible for people from other countries to hear in their own languages about what God had done (Acts 2:6-11). This passage is one of several references to speaking in “other languages” or “tongues” (see also 10:44-48; 19:6; 1 Cor…”
