Isaiah 35:3
Strengthen ye the weak hands, and confirm the feeble knees.
Strengthen ye the weak hands,.... These are the words of the prophet, as the Targum,
"the prophet said, strengthen the weak hands;''
or rather of God, by the prophet, to the converted Gentiles, to those who saw the glory of the Lord; particularly to the ministers of the Gospel, who have to do with weak and feeble persons, who can scarcely lift up their hands, or stand upon their legs, under a sense of sin, in a view of wrath, and immediate ruin and destruction, ready to sink and faint, because of their enemies, or through want of food; and their business is to comfort and strengthen them, by preaching the Gospel, and pointing out the promises of it to them:
and confirm the feeble knees; that so they may keep their ground against their enemies; shake off their fears and trembling; go on their way courageously and rejoicing; run, and not be weary; walk, and not faint: "hands" and "knees" are mentioned particularly, because a man's strength lies greatly in them; and his weakness is seen by the languor and trembling of them.
