'Redemption' in the Bible

Wherefore have I come, and there is no one? I called, and there is none answering, Hath My hand been at all short of redemption? And is there not in me power to deliver? Lo, by My rebuke I dry up a sea, I make rivers a wilderness, Their fish stinketh, for there is no water, And dieth with thirst.

The Lord has bared His holy arm (His infinite power)Before the eyes of all the nations [revealing Himself as the One by Whom Israel is redeemed from captivity],That all the ends of the earth may seeThe salvation of our God.

For I planned the day of vengeance,and the year of My redemption came.
