Seek the Lord. Compare similar counsel by other prophets (Amos 5:4, 6, 8; Zeph. 2:3). Solomon was admonished to set his heart upon one objective. As king, he would find many allurements that would tend to lead him astray. There was only one path of safety, and that was to seek the Lord with all his heart. Such searching is rewarded: “Ye shall seek me, and find me, when ye shall search for me with all your heart” (Jer. 29:13).
Arise therefore, and build. Similar words of encouragement need to be spoken to weak, perplexed, struggling congregations without a suitable house of worship. Sanctuaries of the Lord need to be built, and the only way that they will be built is for men to arise and build them. By passing on his admonition to his son, David was imparting some of his own zeal and spirit to Solomon. In many a community there could be a fitting monument to the cause of the Lord if only men would arise and build.
