He shall abide, or sit, to wit, in the throne, Jeremiah 13:13. Before God; living and ruling as in God's presence, and serving God with his royal power, and worshipping him in his tabernacle. Prepare, or order, or appoint, as this word signifies, Jonah 1:17, Jonah 4:6. Mercy and truth; either,
1. The graces of mercy or compassion, and truth or faithfulness; which are the great supporters of thrones, Proverbs 20:28, Proverbs 29:14. Or rather,
2. Thy mercy and truth, i.e. the effects of them; thy truth in giving me those mercies which thou hast promised to me, and thy mercy in giving me such further blessings as I need and thou seest fit to give me.
