A.T. Robertson Commentary Luke 21:28

"But when these things begin to come to pass, look up, and lift up your heads; because your redemption draweth nigh." — Luke 21:28 (ASV)

Look up (ανακυψατε). First aorist active imperative of ανακυπτω, to raise up. Here of the soul as in Joh 8:7,10, but in Lu 13:11 of the body. These the only N.T. examples of this common verb.

Redemption (απολυτρωσις). Act of redeeming from απολυτροω. The final act at the second coming of Christ, a glorious hope.
