Psalm 16:10 For You will not leave my soul in Sheol, Nor will You allow Your Holy One to see corruption.
Here, a prophecy of Christ' resurrection. Jesus would be crusified, die, but rise the third day. After the third day is the day, the body is corrupted, or breaks down. Jesus rose from the dead. Death could not keep Him. He was without sin. Through His sacrifice, we have victory over death & grave.
