I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.
I command with mine own heart - (Genesis 24:45 .) Lo, I am come to great estate, and have gotten more wisdom - rather, 'I have magnified and gotten' (literally, added, increased), etc.
Than all (they) that have been before me in Jerusalem - namely, the priests, judges, and two kings that preceded Solomon. Melchisedec was one of the kings of the ancient dynasty who is included in the words, "all that have been before me." His earthly wisdom exceeded that of all before Jesus Christ, the antitypical Koheleth, or 'Gatherer of men' (Luke 13:34), and "Wisdom" incarnate (Matthew 11:19; Matthew 12:42; 1 Kings 3:12; 1 Kings 4:29-34; 1 Kings 10:23-24). The wisdom in which Solomon excelled all, by the gift of God was concerning earthly things (Ecclesiastes 1:13). It is of this earthly wisdom and acuteness, viewed by itself that Solomon pronounces that its result is only "sore travail." Brilliant as it was, so that it attracted the notice of the pagan world, it yet is classed only with the possession of worldly goods. In the wisdom that is heavenly Solomon was certainly not above Moses (Numbers 12:3; Numbers 12:6-8; Deuteronomy 34:10-12; James 1:5; James 3:17).
Had ... experience - literally, had seen (Jeremiah 2:31). Contrast with this glowing in worldly wisdom, Jeremiah 9:23-24.
