Proverbs 25 King James Version (KJV)
6 Put not forth thyself in the presence of the king, and stand not in the place of great men:
7 For better it is that it be said unto thee, Come up hither; than that thou shouldest be put lower in the presence of the prince whom thine eyes have seen.
Jesus expressed this idea in The Parable of the Wedding Feast
Luk 14:7 And he put forth a parable to those which were bidden, when he marked how they chose out the chief rooms; saying unto them,
Luk 14:8 When thou art bidden of any man to a wedding, sit not down in the highest room; lest a more honourable man than thou be bidden of him;
Luk 14:9 And he that bade thee and him come and say to thee, Give this man place; and thou begin with shame to take the lowest room.
Luk 14:10 But when thou art bidden, go and sit down in the lowest room; that when he that bade thee cometh, he may say unto thee, Friend, go up higher: then shalt thou have worship in the presence of them that sit at meat with thee.
Luk 14:11 For whosoever exalteth himself shall be abased; and he that humbleth himself shall be exalted.
And this one…
21 If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink:
22 For thou shalt heap coals of fire upon his head, and the Lord shall reward thee.
Paul quotes this here….
Rom 12:20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
