What does Psalm 66:6 mean?
The psalmist reminds the world (Psalm 66:1) about one of God's awesome deeds: turning the Red Sea into dry land for the Hebrews' safe passage. This story is recorded in Exodus chapter 14.The entire nation of Israel had fled from Egypt (Exodus 12:51), but they found themselves hemmed in at the Red Sea with Pharaoh's elite cavalry bearing down on them (Exodus 14:1–4). There was no possible escape; but God can do what men find impossible (Luke 1:37). The Hebrews were afraid and cried out to Lord (Exodus 14:10). They expected to be killed (Exodus 14:11). Moses reassured Israel that God intended to save His people, and that the pursuing Egyptians would never be seen again (Exodus 14:13). At the Lord's direction, Moses gestured over the sea (Exodus 14:16). Then God pushed the water back so the Hebrews could cross on dry land (Exodus 14:21–22). The Egyptians tried to follow, but God let the water return and they were drowned (Exodus 14:23–29). Moses and the people celebrated with a joyful song to the Lord (Exodus 15).
Psalm 66:1–9 opens with a call to praise extended to the entire world. The psalmist declares God's awesome might. He reflects on the Lord's incredible acts of power. Among these are His provision for Israel's safe passage through the Red Sea (Exodus 14:21–22). God is watching the whole earth; no one should arrogantly think they can defy Him. God's people should be particularly worshipful for the ways God has preserved them.
This psalm appeals to the entire world to worship the Lord. His great works, such as giving Israel safe passage through the Red Sea, should be praised. Because God watches the world, no one should presume they can rebel without consequences. God tested Israel heavily but brought the nation to an abundant place. The psalmist declares that he will fulfill his vows and offer sacrifices, because God answered his prayer. Verses 1–9 speak to the nations of earth; verses 10–15 are spoken to God; verses 16–20 are addressed to the congregation.
