An interesting point

Dropping back a tad, note that Luther highlights the distance of Abraham and Isaac's trip to Mt. Moriah which is about three days, (See Gen. 22:4.)

AELW 4:98

"The Lord even designates a definite place away from his home, in the land of Moriah. Furthermore, Moriah is approximately 10 German miles distant from Beer-sheba, unless the cosmographers are mistaken. This is a journey of about three days, for he had a donkey along to carry wood and food. Consequently, their progress was rather slow."

and continuing...

AELW 4:110

Genesis 22:4 "On the third day Abraham lifted up his eyes and saw the place afar off."

"It is my opinion that the place of the sacrifice was not more than a quarter of a mile distant from the place Abraham ordered his servants to halt. Jerusalem, or Mt. Moriah, even though it was a rather high place, nevertheless could not be seen from a distance, because the region round about it was mountainous. I am truly surprised that the father did not die from that bitter and persistent grief, for he had to make a journey of three days. If that struggle had lasted one or two hours, he would have prevailed rather easily. Therefore this delay makes his obedience greater. Meanwhile he thought: “Behold, I am walking along with my son, who is my greatest hope and a young man; he has to die.” During these three days he endured this kind of torture of his flesh and at the same time the darts of Satan. Nevertheless, he had to endure it in silence because of the command, and since he relied on this, he was strengthened and preserved."

Thus is Abraham's three day journey to give up his son. One can only wonder where it was that Abraham camped that third day for he could see Mt. Moriah in the distance. Genesis chapter 21:35, states, Abraham "sojourned many days in the land of the Philistines." So does this mean that Abraham was approaching Mt. Moriah from the West?

Thus Abraham traveled three days to offer his son as a sacrifice. Christ approached Mt. Moriah, and offered Himself as a sacrifice not for one but for all, and His three day journey gives the promise eternal life to all who would believe in Him.
