Job 33:25

then his flesh is restored ¹  like a youth’s; he returns to the days of his youthful vigor. ² 

De 34:7; Jos 14:10,11; 2Ki 5:14; Job 42:16; Ps 103:5; Ho 2:15

¹ tc The word רֻטֲפַשׁ (rutafash) is found nowhere else. One suggestion is that it should be יִרְטַב (yirtav, “to become fresh”), connected to רָטַב (ratav, “to be well watered [or moist]”). It is also possible that it was a combination of רָטַב (ratav, “to be well watered”) and טָפַשׁ (tafash, “to grow fat”). But these are all guesses in the commentaries.

² tn The word describes the period when the man is healthy and vigorous, ripe for what life brings his way.
