Genesis 48:2Meaning & Commentary from the Church Fathers

Observe how his affection for his son empowered him, demonstrating how his inner fortitude triumphed over his frailty. Upon learning of his son's coming, he "sat up on his bed," as noted in Scripture.

I am uncertain why the Seventy translators chose to interpret the same term in differing ways. I can only suggest that the word metta (מִּטָָּֽה), which they have translated as 'bed' in this instance, is seen as 'rod' in the earlier context discussing Jacob's act of worship.

An elderly man lay weakly on his deathbed, at peace. He was informed that his son Joseph was on his way to visit. With renewed effort, he propped himself up on his bed. Was it the love he held for his son that invigorated him? Or was it a moment of divine grace that enveloped him? The man was filled with the vitality of holy inspiration. Frequently, in those chosen by God, a miraculous influence of the Holy Spirit suddenly intermingles with the natural actions of humanity. This powerful intervention lifts an individual above their ordinary condition, transforming them into an instrument of God’s purpose. Such were the final moments of Jacob.
