2 Chronicles 11:17
So they strengthened the kingdom of Judah, and made Rehoboam the son of Solomon strong, three years…
Three years of experimental goodness ought to be three years of personal consolidation. To get three years ahead of the enemy ought to be a great advantage. The doctors say that it takes three years to get drink really out of a man's system and no man is safe until he has quite passed the line of three years. These critical times in life are the making of life, when they are really seized aright as to their spirit and highest significance.
(J. Parks, D. D.).
