John Gill Commentary 1 Kings 8:61

"Let your heart therefore be perfect with Jehovah our God, to walk in his statutes, and to keep his commandments, as at this day." — 1 Kings 8:61 (ASV)

Let your heart therefore be perfect with the Lord your God ,
&c.] Sincere in their love to him, united in their worship of him, and constant in their obedience to him:

to walk in his statutes, and to keep his commandments, as at this day :
as they did that day, neither king nor people having as yet fallen into idolatry, but showing by their then present appearance a zeal for God, his house, and worship.
