II. The use that some of the chambers mentioned before were put to. 1. Some were for the singers, v. 44. It should seem they were first provided for before any other that attended this temple-service, to intimate, not only that the singing of psalms should still continue a gospel-ordinance, but that the gospel should furnish all that embrace it with abundant matter for joy and praise, and give them occasion to break forth into singing, which is often foretold concerning gospel times, Ps. xcvi. 1; xcviii. 1. Christians should be singers. Blessed are those that dwell in God's house, they will be still praising him. 2. Others of them were for the priests, both those that kept the charge of the house, to cleanse it, and to see that none came into it to pollute it, and to keep it in good repair (v. 45), and those that kept the charge of the altar (v. 46), that came near to the Lord to minister to him. God will find convenient lodging for all his servants. Those that do the work of his house shall enjoy the comforts of it.
