'Tottering' in the Bible
"Your words have helped the tottering to stand, And you have strengthened feeble knees.
How long will ye imagine mischief against a man? ye shall be slain all of you: as a bowing wall shall ye be, and as a tottering fence.
A bad tooth, and a tottering foot, Is the confidence of the treacherous in a day of adversity.
Strengthen the weak hands and confirm the tottering knees.
So then, brace up and reinvigorate and set right your slackened and weakened and drooping hands and strengthen your feeble and palsied and tottering knees,
