'Decay' in the Bible

Because You will not abandon my soul to Hades,Nor allow Your Holy One to undergo decay.

he looked ahead and spoke of the resurrection of the Christ, that He was neither abandoned to Hades, nor did His flesh suffer decay.

As for the fact that He raised Him up from the dead, no longer to return to decay, He has spoken in this way: ‘I will give you the holy and sure blessings of David.’

Therefore He also says in another Psalm, ‘You will not allow Your Holy One to undergo decay.’

For David, after he had served the purpose of God in his own generation, fell asleep, and was laid among his fathers and underwent decay;

but He whom God raised did not undergo decay.
