Job 4:4

Thy words have upholden him that was falling . Many a man, just on the point of falling, has been stopped in time by thy wise words and good advice to him. This is a strong testimony to Job's kindliness of heart, and active sympathy with sufferers during the period of his prosperity. And thou hast strengthened the feeble knees ; literally, the bowing knees— those that were just on the point of collapsing and giving way through exhaustion or feebleness (comp. Isaiah 35:3 ).
