V.2 This was the Feast of Tabernacles (see your notes on Lev. 23).
V.3-4 All was godly order here, according to Numbers 4.
V.5 They willingly offered more than they could count.
V.6 The only piece of furniture from the tabernacle which went into the temple.
V.8 The priests could go into “the holy place” but not into “the oracle” (the “holiest of all”), where the ark was. They could see the end of the staves only, but that was enough to remind them that God was with them. The rest of the people of Israel who were “without” (outside the building) did not see any of this. Today we who are Christians are priests and it is our happy privilege to be able to go through the veil into the very presence of God (Heb. 10:19-22).
V.10-11 God proved that He was pleased, by having a cloud (the glory of the Lord) fill the temple. So it was with the beginning of the church (Acts 4:31-33).
V.12-21 The voice of praise and thanksgiving to God out of a full heart!
V.22-30 The voice of prayer and supplication to God out of a dependent heart! Notice the importance of “the place” where the Lord said His Name would be. There was only one such place in all Israel and for all Israel. Compare Matthew 18:20 and see what “the place” is for believers today.
V.31-32 Individual sins were to be settled “in the house” (the Temple), if they could not be settled privately between neighbors (compare Matt. 18:15-17).
