Dress your best for the King of kings; but of course your heart foremost.
Exciting to have a meal with King of Kings. What a privilege.
Three times a year all your men must appear before the Lord your God at the place he will choose: at the Festival of Unleavened Bread, the Festival of Weeks, and the Festival of Tabernacles. No one should appear before the Lord empty-handed: Each of you must bring a gift in proportion to the way the Lord your God has blessed you.
Deuteronomy 16:16-17 NIV
Also, bring the best gift/ offering in obedience to the King’s commandment not for His benefit but for our own benefit.
