Isaiah 44:5

“One shall say, I am the Lord’s, &c.] This expresses the success of the apostles’ ministry, not only among the Jews, but more especially among the Gentiles, who were not called by the name of Jacob and Israel; but now should call themselves by those names, as the following clauses show, being called by grace and converted; when they should openly profess their faith in Christ, claim their interest in him, and acknowledge his property in them, and not be ashamed of the name of Christians; and this one, and another, even many should do. The Lord has a people who are his special and peculiar people, his beloved ones, the objects of his delight and pleasure, his chosen and covenant ones, his…”

“The third clause answers in parallelism to the first, the fourth to the second. I am the Lord's-- (Jer 50:5; Co1 6:19-20; Co2 8:5). call himself by the name of Jacob--The Gentiles (as the result of the outpouring of the Holy Spirit on Israel, the Lord's "seed," first) shall join themselves to the children of Jacob, in order to worship their God (compare Isa 43:7; Psa 49:11). Or, "calls," that is, invokes and celebrates the name of Jacob, attaches himself to his nation and religion [MAURER], (Psa 24:6). subscribe . . . hand unto . . . Lord--in solemn and public covenant, pledging himself to God's service (compare Neh 9:38), before "witnesses" (Heb 12:1), after the manner of a civil contract…”

“One shall say - It shall be common to say this, or a profession of religion shall be common. The various expressions in this verse mean substantially the same thing - that there should prevail among the people a disposition to make a profession of attachment to Yahweh in every proper public manner. It is in immediate connection with what is said in the previous verses, that he would pour his Spirit upon them, and especially on their children. The effect would be, that many would make a public profession of religion. This refers, doubtless, in the main, to the period after their return from the captivity, and to the general prevalence of religion then. But it is also true of the people of God…”

“Israel - The blessing of God upon the Jews shall be so remarkable, that the Gentiles shall join them, and accept the Lord for their God. Isaiah 44:7”

“I am: Deu 26:17-19; Psa 116:16; Jer 50:5; Mic 4:2; Zac 8:20-23, Zac 13:9 subscribe: Neh 9:38, 10:1-29; Co2 8:5 the name: Gal 6:16; Pe1 2:9 Isaiah 44:6”

“When Jehovah has thus acknowledged His people once more, the heathen, to whose giddūphı̄m (blasphemies) Israel has hitherto been given up, will count it the greatest honour to belong to Jehovah and His people. "One will say, I belong to Jehovah; and a second will solemnly name the name of Jacob; and a third will inscribe himself to Jehovah, and name the name of Israel with honour." The threefold zeh refers to the heathen, as in Psa 87:4-5. One will declare himself to belong to Jehovah; another will call with the name of Jacob, i.e., (according to the analogy of the phrase ה בשׁם קרא) make it the medium and object of solemn exclamation; a third will write with his hand (ידו, an acc. of more…”
