Commentaire sur La Genèse 32:32

ויזרח לו השמש AND THE SUN SHONE UPON HIM— This is the expression that people use: “When we reached such-and-such a place the dawn broke upon us”. This is its literal sense. But the Midrash says that לו means, “for his needs” — to heal his lameness. Thus, too, you read in Scripture a similar metaphor (Malachi 3:20) “the sun of righteousness with healing in its wings”. The hours that it had set before its time for his sake when he left Beer-Sheba (cp. Genesis 18:11) it now rose before its time for his sake (Sanhedrin 75b).

והוא צולע על ירכו, now that the sun was shining he realised that he was walking with a limp, a belated discovery, just as when he discovered that he had spent a night in bed with Leah thinking that she was Rachel (29,25).

The sun shone upon him. This verse must be inverted — after he passed Penuel, still limping, the sun shone and healed him. Similarly, in the time to come the “sun” of the redemption will shine and heal the righteous.
