'O God' in the Bible

If a man sins against a man, one may appeal to God on his behalf. But if a man sins against the Lord, who then will intercede for him?" But Eli's sons would not listen to their father, for the Lord had decided to kill them.

"As you continue on from there, you will come to the tall tree of Tabor. At that point three men who are going up to God at Bethel will meet you. One of them will be carrying three young goats, one of them will be carrying three round loaves of bread, and one of them will be carrying a container of wine.
