Arcana Coelestia #2378
2378. That 'the men reached out their hand' means the Lord's powerful aid is clear from the meaning of 'the men' as the Lord, dealt with above, and from the meaning of 'hand' as power, dealt with in 878.
Ezekiel 20:5-6
5
and tell them, Thus says the Lord Yahweh: In the day when I chose Israel, and swore to the seed of the house of Jacob, and made myself known to them in the land of Egypt, when I swore to them, saying, I am Yahweh your God;
6
in that day I swore to them, to bring them forth out of the land of Egypt into a land that I had searched out for them, flowing with milk and honey, which is the glory of all lands.
