For You will not abandon my soul to Sheol, nor will You let Your Holy One see decay.
Christ believed in His resurrection and received it on the third day, His body rising in glorious life while corruption could never touch Him, God's Holy One. This is our rock: He rose, and therefore all His people shall rise, though they see corruption, to everlasting life. Go to your graves as to your beds, for Jesus has led the way through death to glory.
