When Jacob blessed Joseph, he used three titles to describe the God he trusted:
the God who was in covenant with his fathers Abraham and Isaac (28:13; 31:5, 42; 32:9; 46:3);
the God who had been his shepherd (one who guides and cares for his people; see 49:24; Exodus 6:6; Psalm 23:1; Isaiah 59:20); and
the angel (a messenger from God) who had rescued him from all harm.
Jacob prayed the same blessings for Joseph’s sons.
