Comentario sobre Isaías 55:3

the dependable mercies of David For I will repay David for his mercies.

ולכו אלי And come unto me. Lit., Go away from your place toward me; comp. סורה אלי turn in to me (Jud. 4:18).⁶הלך to go signifies removal from the place of him that speaks, בוא to come, approach to it. The preposition אלי demands the verb ובואו, while the verb ולכו demands ממני; I. E. therefore explains the words ולכו אלי as an elliptical phrase, meaning, and go from your place and come unto me. Comp. I. E. on 31:1, Note 2.

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;⁷See I. E. on 49:3. and the meaning of הנאמנים חסדי דוד is in that case: for the kindness of Messiah is sure.⁸That is, is everlasting, and therefore the covenant which will be made with you through him, will likewise be ברית עולם an everlasting covenant. According to the first explanation the everlasting covenant promised here, is compared with the everlasting covenant which God made with King David. This explanation is supported by the next verse.
