And make straight paths for your feet - Margin, “even.” The word used here means properly straight, in the sense of upright, erect; Acts 14:10; but it is used here in the sense of straight horizontally, that is, level, plain, smooth. The meaning is, that they were to remove all obstacles out of the way, so that they need not stumble and fail. There is probably an allusion here to Proverbs 4:25-27. “Let thine eyes look right on, and let thine eyelids look straight before thee. Ponder the path of thy feet, and let all thy ways be established. Turn not to the right hand nor to the left; remove thy foot from evil.” The idea is, that by every proper means they were to make the way to heaven as plain and easy as possible. They were to allow no obstructions in the path over which the lame and feeble might fall.
Lest that which is lame be turned out of the way - A lame man needs a smooth path to walk in. The idea is here, that everything which would prevent those in the church who were in any danger of falling - the feeble, the unestablished, the weak - from walking in the path to heaven, or which might be an occasion to them of falling, should be removed. Or it may mean, that in a road that was not level, those who were lame would be in danger of spraining, distorting, or wrenching a lame limb; and the counsel is, that whatever would have a tendency to this should be removed. Divested of the figure, the passage means, that everything should be removed which would hinder anyone from walking in the path to life.
But let it rather be healed - As in the case of lameness, pains should be taken to heal it rather than to suffer it to be increased by careless exposure to a new sprain or fracture, so it should be in our religious and moral character. Whatever is defective we should endeavor to restore to soundness, rather than to suffer the defect to be increased. Whatever is feeble in our faith or hope; whatever evil tendency there is in our hearts, we should endeavor to strengthen and amend, lest it should become worse, and we should entirely fall.
