Ezekiel 20:6
In the day that I lifted up mine hand unto them, to bring them forth of the land of Egypt into a land that I had espied for them, flowing with milk and honey, which is the glory of all lands: In the day that I lifted up mine hand unto them, to bring them forth of the land of Egypt into a land that I had espied for them, flowing with milk and honey, which is the glory of all lands:
The lifted hand records a solemn pledge to bring Israel out of the land of Egypt into a land personally searched out for them, a land flowing with milk and honey and described as the glory of all lands, revealing deliberate care both in the exodus itself and in the gift of the inheritance. That deliverance was necessary because after long servitude amid Egyptian worship of the sun, moon, stars, and beasts, and images of wood and stone made by human hands, many Hebrews had lost the knowledge of the true God as Maker of the heavens and the earth. They had forgotten His law and had joined in that worship, while only a faithful few preserved the true knowledge.
The promise aimed to bring them into a new country where they would be rid of idolatry and its corrupting influences. That freedom from corrupting surroundings was what the faithful remnant sought when they cried to the Lord for deliverance from the Egyptian yoke. Many others had become so corrupted and so content to remain in bondage rather than face the difficulties of the journey that God did not deliver them by the first display of signs and wonders before Pharaoh.
Instead He overruled events to allow Pharaoh's tyrannical spirit to develop more fully and to manifest His great power before both the Egyptians and Israel. By that fuller revelation of power He sought to make His people anxious to leave Egypt and to choose the service of God.
