2 Chronicles 5:11-14 – “And when the priests came out of the Holy Place (for all the priests who were present had consecrated themselves, without regard to their divisions, and all the Levitical singers, Asaph, Heman, and Jeduthun, their sons and kinsmen, arrayed in fine linen, with cymbals, harps, and lyres, stood east of the altar with 120 priests who were trumpeters; and it was the duty of the trumpeters and singers to make themselves heard in unison in praise and thanksgiving to the Lord), and when the song was raised, with trumpets and cymbals and other musical instruments, in praise to the Lord, ‘For he is good, for his steadfast love endures forever,’ the house, the house of the Lord, was filled with a cloud, so that the priests could not stand to minister because of the cloud, for the glory of the Lord filled the house of God.”
At the dedication of the temple that Solomon built we find 120 trumpeters. These 120 trumpeters were to make themselves heard in unison in praise and thanksgiving to the Lord. When they did so, the glory of the Lord filled the house.
What is this a picture of? Could it be the day of Pentecost when the Holy Spirit was poured out the 120 disciples who spoke in tongues to all those who had gathered from the nations?
Speaking of the disciples and the women with them, Acts 1:14-15 says the 120 disciples were with one accord devoting themselves to prayer. In Acts 2, on the day of Pentecost, the Holy Spirit comes with a mighty sound and fills them and they spoke as the Spirit gave them utterance. At the sound of this taking place, the multitude gathers together. What did they hear? Acts 2:11 says, “We hear them telling in our own tongues the mighty works of God.” These 120 disciples made “themselves heard in unison in praise and thanksgiving to the Lord.”
These 120 disciples were trumpeters. One of the functions of a trumpet in the Bible was to call together the assembly. In Exodus 19-20, the nation of Israel is called together with a trumpet to Mount Sinai so that God can give them his covenant. In Acts 2, Jews were gathered from every nation to hear the 120 trumpeters singing the praises of God. The scattered Jews were being called to a new covenant, the one Jesus declared the night before he was crucified.
In 2 Chronicles 5 above we read “for he is good, for his steadfast love endures forever.” Steadfast love is the language of God’s covenant. Peter says the events in Acts 2 are happening in fulfillment of God’s plan. Peter quotes a passage from Joel that says God was pouring out his Spirit on all flesh in the last days. What do we read in 2 Chronicles 5 above? “The glory of the Lord filled the house of God.” This was the beginning of the knowledge of God covering the earth as the waters cover the sea.
