Ibn Ezra, on Isa 55:3

“Incline your ear and come to me: hear and your soul shall lire, and I will make an everlasting covenant with you, the faithful mercies of David.”

“ולכו אלי And come unto me. Lit., Go away from your place toward me; comp. סורה אלי turn in to me (Jud. 4:18). And your soul shall live. That is, your soul shall live for ever after the death of the body, or you will receive new life through Messiah, when you will return to the Divine Law. An everlasting covenant, that will never expire. The sure mercy of David, that is, like the covenant which I made with David and the kindness which I showed to him, promising him my mercy will I keep for him for evermore, etc. (Ps. 89:29). It is also possible, that by David in this verse Messiah is meant, who will be of the family of David; as the prophet is sometimes called Israel for the same reason; and the meaning of הנאמנים חסדי דוד is in that case: for the kindness of Messiah is sure. This explanation is supported by the next verse.”
