'Offer' in the Bible

I chose your ancestor from all the tribes of Israel to be my priest, to offer sacrifice on my altar, to burn incense, and to bear the ephod before me. I gave to your ancestor's house all the fire offerings made by the Israelites.

You will go down to Gilgal before me. I am going to join you there to offer burnt offerings and to make peace offerings. You should wait for seven days, until I arrive and tell you what to do."

I thought, 'Now the Philistines will come down on me at Gilgal and I have not sought the Lord's favor.' So I felt obligated to offer the burnt offering."
