1 Kings 2:4

Confirm his word, i.e. fulfil his promise, the condition upon which it was suspended being performed. Take heed to their ways, i.e. diligently observe all their actions, to order them according to God's word. To walk before me; to live as those that have God before their eyes, and endeavour to approve themselves to him. In truth; not only in pretence and show, but truly and sincerely. With all their heart, and with all their soul, i.e. universally, freely, and fervently. There shall not fail thee a man on the throne of Israel; the succession shall be continued in thy line without any interruption.
