The old malignity remains in the unconverted heart, and a watchful eye should be kept on those who, like Shimei, have manifested their enmity, but have given no evidence of repentance. No engagements or dangers will restrain worldly men; they go on, though they forfeit their lives and souls. Let us remember, God will not accommodate his judgment to us. His eye is over us; and let us strive to walk as in his presence. Let our every act, word, and thought, be governed by this great truth, that the hour is quickly coming when the smallest circumstances of our lives shall be brought to light, and our eternal state be fixed by a righteous and unerring God. Thus Solomon's throne was established in peace, as the type of the Redeemer's kingdom of peace and righteousness. And it is a comfort, in reference to the enmity of the church's enemies, that, how much soever they rage, it is a vain thing they imagine. Christ's throne is established, and they cannot shake it.

Matthew Henry's Commentary on 1 Chronicles 24:3
The divisions of the priests and Levites.
When every one has, knows, and keeps his place and work, the more there are the better. In the mystical body of Christ, every member has its use, for the good of the whole. Christ is High Priest over the house of God, to whom all believers, being made priests, are to be in subjection. In Christ, no difference is made between bond and free, elder and younger. The younger brethren, if faithful and sincere, shall be no less acceptable to Christ than the fathers. May we all be children of the Lord, fitted to sing his praises for ever in his temple above.
