He himself went on ahead and bowed down to the ground seven times as he approached his brother.
Genesis 33:3 (NIV)
There’s a note in the teachings of Rabbeinu Bahya that say that Jacob bowing to the ground seven times is a nod to a teaching found in Proverbs.
for though the righteous fall seven times, they rise again,
but the wicked stumble when calamity strikes.
Proverbs 24:16 (NIV)
