Matthew Henry on Genesis 33:17-20

Jacob did not content himself with words of thanks for God's favour to him, but gave real thanks. Also he kept up religion, and the worship of God in his family. Where we have a tent, God must have an altar. Jacob dedicated this altar to the honour of El-elohe-Israel, God, the God of Israel; to the honour of God, the only living and true God; and to the honour of the God of Israel, as a God in covenant with him. Israel's God is Israel's glory. Blessed be his name, he is still the mighty God, the God of Israel. May we praise his name, and rejoice in his love, through our pilgrimage here on earth, and for ever in the heavenly Canaan.
