Know thou the God of thy father - "Knowing God," in the sense of having a religious trust in Him, is an unusual phrase in the earlier Scriptures. It scarcely occurs elsewhere in the historical books. David, however, uses the phrase in his Psalms Psa 36:10; and its occurrence here may be accepted as evidence that the entire speech is recorded in the actual words of the monarch.

And thou, Solomon my son,.... Who was present in this assembly, and presented to them by David as his successor, and their future king: and having addressed them, he turns himself to him, and exhorts him, saying:

know thou the God of thy father; who was his Father and covenant God, and whom he served and worshipped, and who had bestowed upon him many favours, both temporal and spiritual; and having had such an experience of his goodness, he exhorts his son to seek to know more and more of him, and to own and acknowledge him as his God, and to love and fear him:

serve him with a perfect heart, and with a willing mind; cordially and sincerely, cheerfully and freely, neither in an hypocritical manner, nor through force and constraint, nor with loathing and weariness:

for the Lord searcheth all hearts; the hearts of all men, even of kings, and knows from what principles and with what views and in what manor they serve him:

and understandeth all the imaginations of the thought; not only the thoughts of the heart, when regularly formed and ranged in order, hut even the very beginning of them, the first motions of the mind, and before they are well formed, see Genesis 6:5.

if thou seek him; by prayer and supplication in his house and ordinances:

he will be found of thee; grant his presence and bestow his favours, see Isaiah 4:6.

but if thou forsake him: his word, his ways, his worship:

he will cast thee off for ever; from being king, or enjoying that peace, prosperity, and happiness, which otherwise would be enjoyed.

And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the LORD searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.

28:9 Know - So as to love and serve him. Words of knowledge in scripture - use commonly imply affection and practice. Or, acknowledge him, as thy God, by loving and obeying him. Searcheth - If thou dost only put on a profession of religion to please me, or if thy obedience to God be unsincere, thou mayest indeed deceive me, but thou canst not deceive him, for he searcheth the motions of thy heart. Cast thee off - Notwithstanding all his promises to me and to my seed, and that great honour and favour which he hath shewed thee.

1Ch 28:9-20. He Encourages Solomon to Build the Temple.

9, 10. And thou, Solomon my son-The royal speaker now turns to Solomon, and in a most impressive manner presses upon him the importance of sincere and practical piety.

know thou-He did not mean head knowledge, for Solomon possessed that already, but that experimental acquaintance with God which is only to be obtained by loving and serving Him.

28:1-10 During David's last sickness, many chief priests and Levites were at Jerusalem. Finding himself able, David spoke of his purpose to build a temple for God, and of God's disallowing that purpose. He opened to them God's gracious purposes concerning Solomon. David charged them to cleave stedfastly to God and their duty. We cannot do our work as we should, unless we put on resolution, and fetch in strength from Divine grace. Religion or piety has two distinct parts. The first is knowledge of God, the second is worship of God. David says, Know thou the God of thy father, and serve him with a perfect heart and a willing mind. God is made known by his works and word. Revelation alone shows the whole character of God, in his providence, his holy law, his condemnation of sinners, his blessed gospel, and the ministration of the Spirit to all true believers. The natural man cannot receive this knowledge of God. But thus we learn the value of the Saviour's atonement, and of the sanctification of the Holy Spirit, and are influenced to walk in all his commandments. It brings a sinner to his proper place at the foot of the cross, as a poor, guilty, helpless worm, deserving wrath, yet expecting every thing needful from the free mercy and grace of God our Father, and the Lord Jesus Christ. Having been forgiven much, the pardoned sinner learns to love much.
