And the angel which I saw stand upon the sea and upon the earth,.... His right foot being on the one, and his left foot upon the other, as described in Re 10:2;lifted up his hand to heaven; the Oriental versions read, "his right hand"; and so some copies, and the Complutensian edition: the man clothed in linen, Da 12:6, who is the same with the angel here, held up both his hands; the lifting up of the hand was a gesture used in swearing: see Ge 14:22; so the Jews say , "the right hand", or by the right hand, hewby wz, "this is an oath", according to Da 12:7; or whether the right hand or the left, is an oath, according to Isa 62:8.
