Genesis 49:1

Jacob called unto his sons. Jacob now revealed to his 12 sons his spiritual bequest. Solemnly he exhorted them to listen to the things he was about to say. As Isaac, by virtue of divine foresight, had in his blessing (ch. 27) pointed out prophetically to Jacob and Esau the future history of their families, so in broad outline the future of the entire nation, as represented by the 12 sons, was pictured by Jacob. Although the characters of his sons formed the starting point of his prophecies concerning them, the Spirit of God revealed to the dying patriarch the future history of his seed, so that he discerned in the characters of his sons the future development of the tribes descending from them. To each he assigned its position and importance in the nation, with unerring prophetic insight.

In the last days. Literally, “at the end of days.” This is not a reference to the end of this world’s history, as in some other prophetic utterances, nor does it refer merely to the Messianic age as the close of Jewish history. Here it simply means “in the future.”
