For. I lift up my, hand to heaven. Others render it, "When I shall have lifted up my hand," and read it connectedly with the foregoing verse, that God's power in destroying and preserving will be manifest, if He raises up His hand to heaven. I do not doubt, however, but that it is the beginning of a new sentence, and that God thus commences, in order to affirm more strongly what He immediately adds respecting the future destruction of their enemies. If, however, any prefer the adverb of time "when," I have no great objection to offer, provided these clauses are connected, "As soon as I shall have lifted up my hand to heaven, I will put to confusion the enemies of my Church." To lift up the hand is explained in two ways; for some suppose it to be a manifestation of power, as men are wont, by the uplifting of their hand, to glow, when they are confident in their strength, and despise their enemies. Others, however, more correctly state it to be a form of adjuration God, who is exalted above all heavens, cannot, indeed, be literally said to lift His hand; but it is no new thing for Him to borrow modes of expression taken from men's common habits and customs, especially when He suddenly rises again to sublimity, after having appeared for a while to sink below the level of His greatness. Certainly the words which follow contain in them an oath, "I live for ever;" and hence it is probable [1] that the elevation of His hand was expressive of His taking the oath. God swears by His life in a very different sense from men. Sometimes, indeed, He adopts our common modes of speaking, as when He is said to swear by His soul; but here, "I live," is tantamount to His swearing by Himself, or by His eternal essence.

Footnotes

1 - I hardly understand the hypothetical form in which this sentence is put, after what C. has already said on this point on Exodus 6:8 ([46]vol. 1, p. 131,) and on Numbers 14:30 (ante, [47]p. 81.) Perhaps he merely meant that the coincidence of the adjuration with the uplifting of the hand fixed the sense of the latter expression in this place.

For I lift up my hand to heaven - See concerning oaths and appeals to God in the note on Deuteronomy 6:13 (note).

For I (t) lift up my hand to heaven, and say, I live for ever.
(t) That is, I swear, read (Genesis 14:22).

For I lift up my hand to heaven,.... Which is a gesture used in swearing, Genesis 14:22, and is ascribed to a divine Person, Ezekiel 20:5; and particularly to Christ the angel, that is so wonderfully described, Revelation 10:1; though sometimes it is used, as Aben Ezra observes, to excite the attention of hearers, but here it signifies swearing; and so the Targums of Jonathan and Jerusalem paraphrase it,"I have lift up my hands with an oath to heaven;''and to the same sense is the Septuagint version:
and say, I live for ever; which is the form of an oath; when men swear, they are to swear, the Lord liveth, or to swear by the living God, and him only, Jeremiah 4:2; and when the Lord swears in this manner, he swears by his life, by himself, because he can swear by no greater; and his form of swearing is, "as truly as I live, saith the Lord", Numbers 14:21; so the above angel is said to swear by him that liveth for ever and ever, Revelation 10:6; and since Christ is the living God, without beginning of days, and end of life, and lives for evermore, he may be thought to swear by himself, by his own life, which is for ever; and as the oath of the Lord is used in condescension by him, to confirm the faith of his people in the immutability of his counsel and promises, and to ascertain unto them the sure performance of them; so it is also used to assure wicked men of the certain performance of his threatenings; and it is as if Christ here said, as sure as I am the living God, and do and shall live for ever, I will most certainly do the things which next follow.

I lift up my hand - I solemnly swear, that I will do what here follows. I live - As sure as I live.
