'Palsied' in the Bible

The king [of Judah] will mourn and the prince (Zedekiah) will be clothed with [garments of] despair and anguish, and the hands of the people of the land shall tremble [in terror]. I will deal with them in accordance with their conduct, and by their judgments I will judge them. And they will know [without any doubt] that I am the Lord.’”

So then, strengthen hands that are weak and knees that tremble.
