“When Israel went out from Egypt, the house of Jacob from a people of strange language, Judah became God’s sanctuary, Israel his dominion.” (Psalm 114: 1 – 2)
When the Hebrews left Egypt, the Lord God claimed the called and chosen people as the Divine’s own again. No longer under the rule of Pharaoh, the people of God had to learn how to live as God’s people again. As I said, very tough lessons to learn. But this psalm does not dwell and focus on the people of God, but on the Lord God and might it took to reclaim the Divine’s called and chosen people.
