1 Chronicles 29:18 - Joseph Benson’s Commentary on the Old and New Testaments

O Lord God of Abraham, &c. A God in covenant with them, and with us for their sakes. Keep this for ever, &c. Since it is from thy grace that thy people have such willing minds, continue that grace to them, that they may persist in the same generous disposition toward thee and thy worship. And grant that by our perseverance in this piety and charity, we may make good our part of the covenant, and so may not forfeit the benefit of it. And prepare their heart unto thee Or rather, as it is in the margin, stablish or confirm their heart. Thou, who hast begun a good work, confirm and carry it on by thy grace, otherwise it will languish, and this very people will prove degenerate.
