[They are] new every morning,.... That is, the tender mercies or compassions of God are, which prove that they fail not; there are instances of them every day, not only in a temporal, but in a spiritual sense; they are ever new, always fresh and vigorous, constant and perpetual; such are the love, grace, and mercy of God, though of old, yet daily renewed in the manifestations thereof; and which make a morning of spiritual light, joy, and comfort; and whenever it is morning with the saints, they have new discoveries of the love of God to them; and these indeed are a bright morning to them, a morning without clouds;great [is] thy faithfulness; some render it "thy faith concerning thee" ; this is a great grace, it is the gift of God, the operation of his Spirit, and to exercise it is a great thing; to this purpose is Jarchi's note,"great is thy promise, and a great thing it is to believe in thee, that it shall be performed, and that thou wilt observe or keep what thou hast promised to us;''but the attribute of God's faithfulness is rather meant; which is another reason why the people of God are not consumed, since that never fails; God is faithful to himself, and cannot deny himself; he is faithful to his counsels and purposes, which shall be truly accomplished; and to his covenant and promises, which shall be fulfilled; and to his Son, the surety and Saviour of his people.
