Verse 20. He erected an altar -
1. In thankfulness to God for the good hand of his providence over him.
2. That he might keep up religion, and the worship of God in his family. He dedicated this altar to the honour of El-elohe-israel, God-the God of Israel: to the honour of God in general, the only living and true God, the Best of beings, the First of causes: and to the honour of the God of Israel, as a God in covenant with him. God had lately called him by the name of Israel; and now he calls God the God of Israel; though he be called a prince with God, God shall still be a prince with him, his Lord and his God.
