Malachi 3:6

6 Forsooth I am the Lord, and I am not changed; and ye sons of Jacob be not wasted. (Yea, I am the Lord, and I do not change; and so ye sons of Jacob be not completely lost, or separated from me.)

Malachi 3:6 Meaning and Commentary

Malachi 3:6

For I [am] the Lord
Or Jehovah; a name peculiar to the most High, and so a proof of the deity of Christ, who here speaks; and is expressive of his being; of his self-existence; of his purity and simplicity; of his immensity and infinity; and of his eternity and sovereignty: I change not;
being the same today, yesterday, and forever; he changed not in his divine nature and personality by becoming man; he took that into union with him he had not before, but remained the same he ever was; nor did he change in his threatenings of destruction to the Jews, which came upon them according to his word; nor in his promises of his Spirit, and presence, and protection to his people; nor will he ever change in his love and affections to them; nor in the efficacy of his blood, sacrifice, and righteousness; wherefore, as this is introduced to assure the truth and certainty of what is said before, concerning his being a swift witness against the wicked, so also for the comfort of the saints, as follows. The Targum is,

``for I the Lord have not changed my covenant.''

Therefore ye sons of Jacob are not consumed;
such who were Israelites indeed, true believers in Christ; these were not consumed when the wicked Jews were, but were directed to leave the city before its destruction, and go to another place, as they did, whereby they were preserved; and so it was, that not one Christian perished in it; (See Gill on Matthew 24:13) and so it is owing to the unchangeable love, grace, and power of Christ, that none of his perish internally or eternally, but have everlasting life.

Malachi 3:6 In-Context

4 And the sacrifice of Judah and of Jerusalem shall please the Lord, as the days of the world, and as old years. (And then the sacrifices, or the offerings, of Judah and of Jerusalem shall please the Lord, like in the days of old, and like in the years long ago.)

5 And I shall come to you in doom, and I shall be a swift witness to mis-doers, either enchanters of devil's craft, and to adulterers, and to forsworn men, and that falsely challenge the hire of an hired man, and widows, and fatherless children, and oppress a pilgrim, and dreaded not me, saith the Lord of hosts. (And I shall come to you in judgement, and I shall be a swift witness against all evil-doers, that is, enchanters of the devil's craft, and adulterers, and perjurers, and those who cheat hired men out of their wages, and do wrong to widows, and fatherless, or motherless, children, and foreigners, yea, those who do not fear me/yea, those who do not revere, or respect, me, saith the Lord of hosts.)

6 Forsooth I am the Lord, and I am not changed; and ye sons of Jacob be not wasted. (Yea, I am the Lord, and I do not change; and so ye sons of Jacob be not completely lost, or separated from me.)

7 Forsooth from the days of your fathers ye went away from my lawful things, and kept not; turn ye again to me, and I shall again turn to you, saith the Lord of hosts. And ye said, In what thing shall we turn again? (Though from the days of your forefathers ye went away from my laws, and did not keep them; return ye to me, and I shall return to you, saith the Lord of hosts. And ye said, How can we return to thee?/Though from the days of your forefathers ye went away from my laws, and did not keep them; turn ye back to me, and I shall turn back to you, saith the Lord of hosts. And ye said, How do we turn back to thee?)

8 If a man shall torment God, for ye tormented me. And ye said, In what thing tormented we thee? In tithes and in first fruits; (Shall a man rob God, for ye have robbed me. And ye said, How have we robbed thee? In the matter of tithes and of first fruits;)
