a Bible passage
You shall leave your name to my chosen to use as a curse,
and the Lord God will put you to death;
but to his servants he will give a different name.
15. curse—The name of "Jew" has been for long a formula of execration (compare Jer 29:22); if one wishes to curse another, he can utter nothing worse than this, "God make thee what the Jew is!" Contrast the formula (Ge 48:20) [Maurer].
my chosen—the elect Church, gathered from Jews and Gentiles, called by "another name," Christians (Ac 11:26). However (see on Isa 65:13), as "My chosen," or "elect," in Isa 65:9, refers to the "seed of Jacob," the believing Jews, hereafter about to possess their land (Isa 65:19, 22), are ultimately meant by "My chosen," as contrasted with the unbelieving Jews ("ye"). These elect Jews shall be called by "another," or a new name, that is, shall no longer be "forsaken" of God for unbelief, but shall be His "delight" and "married" to Him (Isa 62:2, 4).
thee—unbelieving Israel. Isaiah here speaks of God, whereas in the preceding sentences God Himself spake. This change of persons marks without design how completely the prophet realized God with him and in him, so that he passes, without formally announcing it, from God's words to his own, and vice versa, both alike being from God.
