'Right hand' in the Bible

And I heard the man [who] was clothed in linen who [was] above the water of the stream, and he raised his right hand and his left hand to heaven and he swore {by the one who lives forever} that [an] appointed time, appointed times, and half [an appointed time] [would pass] when [the] shattering of {the power of the holy people} {would be completed}; [then] all these things will be accomplished.
