Psalms 71:18 - Exposition

Now also when! am old and greyheaded, O God, forsake me not. Surely, then, thou wilt not forsake me when my youth has fled, and my time of weakness and decay has arrived, so that I need thee all the more. At the time of Adonijah's rebellion, David was "old and stricken in years" ( 1 Kings 1:1 )—nearly, if not quite, seventy years of age ( 2 Samuel 5:4 ). Until I have showed thy strength (literally, thine own ) unto this generation, and thy power to every one that is to come . The psalmist calls on God to sustain him in his old age, not for his own sake, but that he may impress on the rising generation God's might and marvellous acts.
