“But--rather, "For." he--Jacob. work of mine hands--spiritually, as well as physically (Isa 19:25; Isa 60:21; Eph 2:10). By Jehovah's agency Israel shall be cleansed of its corruptions, and shall consist wholly of pious men (Isa 54:13-14; Isa 2:1; Isa 60:21). midst of him--that is, his land. Or else "His children" are the Gentiles adopted among the Israelites, his lineal descendants (Rom 9:26; Eph 3:6) [HORSLEY].”

The work - The children, not of the flesh, but of the promise, whom I, by my almighty grace, have regenerated. In the midst - Incorporated with the Jews, into one and the same body. Shall sanctify - They shall glorify God, with them and for them. Isaiah 29:24”
