Wherefore lift up the hands which hang down, and the feeble knees;
He addresses them as runners, pugilists, warriors (Chrysostom).
Wherefore - resumed from Hebrews 12:1.
Lift up, х anorthoosate (G461), 'erect']. In Isaiah 35:3-4, it is, "Strengthen ye the weak hands." The hand is the symbol of strength.
Feeble, х paralelumena (G3886)] - 'paralyzed:' used only by Luke, Paul's companion. The exhortation has three parts: the first relates to ourselves, Hebrews 12:12-13; the second, to others, Hebrews 12:14, "peace with all men;" the third, to God, "holiness, without which," etc.: the first is referred to in Hebrews 12:15, "lest any man fail of the grace of God;" the second, in "lest any root of bitterness," etc.; the third in Hebrews 12:16, "Lest there be any ... profane person," etc. This threefold relation often occurs in Paul's letters. Note, Titus 2:12. The Greek active, not the middle, requires the sense, Lift up not only your own hands and knees, but also those of your brethren (cf. Hebrews 12:15).
