31 The hoary head is a crown of glory, if it be found in the way of righteousness.

      Note, 1. It ought to be the great care of old people to be found in the way of righteousness, the way of religion and serious godliness. Both God and man will look for them in that way; it will be expected that those that are old should be good, that the multitude of their years should teach them the best wisdom; let them therefore be found in that way. Death will come; the Judge is coming; the Lord is at hand. That they may be found of him in peace, let them be found in the way of righteousness (2 Pet. iii. 14), found so doing, Matt. xxiv. 46. Let old people be old disciples; let them persevere to the end in the way of righteousness, which they long since set out in, that they may then be found in it. 2. If old people be found in the way of righteousness, their age will be their honour. Old age, as such, is honourable, and commands respect (Thou shalt rise up before the hoary head, Lev. xix. 32); but, if it be found in the way of wickedness, its honour is forfeited, its crown profaned and laid in the dust, Isa. lxv. 20. Old people therefore, if they would preserve their honour, must still hold fast their integrity, and then their gray hairs are indeed a crown to them; they are worthy of double honour. Grace is the glory of old age.

      6 Children's children are the crown of old men; and the glory of children are their fathers.

      They are so, that is, they should be so, and, if they conduct themselves worthily, they are so. 1. It is an honour to parents when they are old to leave children, and children's children, growing up, that tread in the steps of their virtues, and are likely to maintain and advance the reputation of their families. It is an honour to a man to live so long as to see his children's children (Ps. cxxviii. 6; Gen. l. 23), to see his house built up in them, and to see them likely to serve their generation according to the will of God. This crowns and completes their comfort in this world. 2. It is an honour to children to have wise and godly parents, and to have them continued to them even after they have themselves grown up and settled in the world. Those are unnatural children who reckon their aged parents a burden to them, and think they live too long; whereas, if the children be wise and good, it is as much their honour as can be that thereby they are comforts to their parents in the unpleasant days of their old age.

      29 The glory of young men is their strength: and the beauty of old men is the gray head.

      This shows that both young and old have their advantages, and therefore must each of them be, according to their capacities, serviceable to the public, and neither of them despise nor envy the other. 1. Let not old people despise the young, for they are strong and fit for action, able to go through business and break through difficulties, which the aged and weak cannot grapple with. The glory of young men is their strength, provided they use it well (in the service of God and their country, not of their lusts), and that they be not proud of it nor trust to it. 2. Let not young people despise the old, for they are grave, and fit for counsel, and, though they have not the strength that young men have, yet they have more wisdom and experience. Juniores ad labores, seniores ad honores--Labour is for the young, honour for the aged. God has put honour upon the old man; for his gray head is his beauty. See Dan. vii. 9.
