Exodus 13:3
And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place: there shall no leavened bread be eaten. And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place: there shall no leavened bread be eaten.
This word belongs to the history of Israel's deliverance from Egypt. In that deliverance the people were led by Jesus Christ, present in the pillar of cloud.
The strength of hand is that God redeemed His people out of the land of Egypt with a strong hand and a stretched-out arm because He was determined to rescue them from slavery and cruel servitude. Those He redeemed He set on high to be a sign and a hope to all in the same condition. By them He teaches everyone to put trust in God and cry to Him, for He will deliver them and magnify His name.
