Exodus 6:5
And I have also heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant. And I have also heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant.
God heard the groaning and cries of the children of Israel held in bondage by the Egyptians. The faithful among them cried for deliverance because they were distressed by the idolatry surrounding them and wanted to leave Egypt to serve God. In hearing them, God remembered the covenant he had made with their ancestors and forefathers. That covenant was to give them Canaan, where they had lived as strangers.
His remembrance assured Moses that the covenant would be faithfully fulfilled in Israel's deliverance. That fulfillment means He will act against Pharaoh to bring the people out of bondage. Because many Hebrews were content to remain in bondage, God did not deliver them at the first display of signs and wonders, but allowed events to reveal Pharaoh's tyranny and to show His own power, so as to make His people eager to leave Egypt and choose His service. The verse applies to God's people laboring against strong opposition to warn others and urge them to change, at great cost to themselves.
