“And both the singers and the porters kept the ward of their God, and the ward of the purification, according to the commandment of David, and of Solomon his son.”
King James Version (KJV)
Matthew Henry's Concise Commentary
12:44-47 When the solemnities of a thanksgiving day leave such impressions on ministers and people, that both are more careful and cheerful in doing their duty, they are indeed acceptable to the Lord, and turn to good account. And whatever we do, must be purified by the blood of sprinkling, and by the grace of the Holy Spirit, or it cannot be acceptable to God.
“And it shall come to pass in that day, that the mountains shall drop down new wine, and the hills shall flow with milk, and all the rivers of Judah shall flow with waters, and a fountain shall come forth of the house of the LORD, and shall water the valley of Shittim.”
