Offenbarung 10:5

lifted up his hand--So A and Vulgate read. But B, C, Aleph, Syriac, and Coptic, ". . . his right hand." It was customary to lift up the hand towards heaven, appealing to the God of truth, in taking a solemn oath. There is in this part of the vision an allusion to Dan 12:1-13. Compare Rev 10:4, with Dan 12:4, Dan 12:9; and Rev 10:5-6, end, with Dan 12:7. But there the angel clothed in linen, and standing upon the waters, sware "a time, times, and a half" were to interpose before the consummation; here, on the contrary, the angel standing with his left foot on the earth, and his right upon the sea, swears there shall be time no longer. There he lifted up both hands to heaven; here he has the little book now open (whereas in Daniel the book is sealed) in his left hand (Rev 10:2), and he lifts up only his right hand to heaven.

This chapter is an introduction to the latter part of the prophecies of this book. Whether what is contained between this and the sounding of the seventh trumpet (Rev 11:15) be a distinct prophecy from the other, or only a more general account of some of the principal things included in the other, is disputed by our curious enquirers into these abstruse writings. However, here we have, I. A remarkable description of a very glorious angel with an open book in his hand (Rev 10:1-3). II. An account of seven thunders which the apostle heard, as echoing to the voice of this angel, and communicating some discoveries, which the apostle was not yet allowed to write (Rev 10:4). III. The solemn oath taken by him who had the book in his hand (Rev 10:5-7). IV. The charge given to the apostle, and observed by him (Rev 10:8-11).

10:5-6 While raising one’s right hand is common in taking an oath today, it is rare in biblical literature (cp. Gen 14:22; 24:9; Dan 12:7). • When making an oath, Jews were very careful not to swear lightly by God’s name (see Exod 20:7). Jesus also rebuked insincere oath-taking (see Matt 5:33-37; 23:16-22). When God swore an oath, he did so in his own name as the highest possible point of reference (see Gen 22:16; Ps 89:35-36; Jer 22:5; Heb 6:13-18).
