Worship- an act of sacrificial obedience.The very first time 'worship' is mentioned in the bible- Genesis 22:5.
"(Abraham) said to his servants, "Stay here with the donkey while I and the boy go over there. We will worship and then we will come back to you."
Just before he offered Issac on the altar to the Lord.
Wow. Can I worship you Lord, like that?
