'Undergo' in the Bible

For Thou wilt not leave me in the Unseen World forsaken, nor give up Thy holy One to undergo decay.

with prophetic foresight he spoke of the resurrection of the Christ, to the effect that He was not left forsaken in the Unseen World, nor did His body undergo decay.

Because in another Psalm also He says, 'Thou wilt not give up Thy Holy One to undergo decay.'

For David, after having been useful to his own generation in accordance with God's purpose, did fall asleep, was gathered to his forefathers, and did undergo decay.
