V. 12.— Wherefore lift up the hands which hang down, and the feeble knees. This may either refer to themselves or others. If the former, those whose hands hang down, and their knees are feeble through weariness and fatigue, are exhorted to lift them up, to resume their courage. If it refers to others, it is an exhortation to bear one another’ s burdens, to take a lively interest in the welfare of their brethren, and to endeavour to animate and encourage them, sympathizing with them in their sorrows, and to comfort and exhort each other by the motives which had been suggested.
