12 And as the sun was just going down, a deep sleep fell upon Abram; and behold, a horror, a great darkness, fell upon him. 13 And he said to Abram, Know assuredly that thy seed will be a sojourner in a land [that is] not theirs, and they shall serve them; and they shall afflict them four hundred years. 14 But also that nation which they shall serve I will judge; and afterwards they shall come out with great property. 15 And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age.

Commentary on Genesis 15:12-16
(Read Genesis 15:12-16)
A deep sleep fell upon Abram; with this sleep a horror of great darkness fell upon him: a sudden change. The children of light do not always walk in the light. Several things were then foretold. 1. The suffering state of Abram's seed for a long time. They shall be strangers. The heirs of heaven are strangers on earth. They shall be servants; but Canaanites serve under a curse, the Hebrews under a blessing. They shall be suffers. Those that are blessed and beloved of God, are often sorely afflicted by wicked men. 2. The judgment of the enemies of Abram's seed. Though God may allow persecutors and oppressors to trample upon his people a great while, he will certainly reckon with them at last. 3. That great event, the deliverance of Abram's seed out of Egypt, is here foretold. 4. Their happy settlement in Canaan. They shall come hither again. The measure of sin fills gradually. Some people's measure of sin fills slowly. The knowledge of future events would seldom add to our comfort. In the most favoured families, and most happy lives, there are so many afflictions, that it is merciful in God to conceal what will befall us and ours.
