Proverbs 25:21-22

25:21 If your enemy is hungry, give him food to eat,

and if he is thirsty, give him water to drink,

25:22 for you will heap coals of fire on his head, ¹ 

and the Lord will reward you. ² 

Matthew 5:44

5:44 But I say to you, love your enemy and ³  pray for those who persecute you,

Romans 12:20-21

12:20 Rather, if your enemy is hungry, feed him; if he is thirsty, give him a drink; for in doing this you will be heaping burning coals on his head. ⁴  12:21 Do not be overcome by evil, but overcome evil with good.

[25:22]  ¹ sn The imagery of the “burning coals” represents pangs of conscience, more readily effected by kindness than by violence. These coals produce the sharp pain of contrition through regret (e.g., 18:19; 20:22; 24:17; Gen 42-45; 1 Sam 24:18-20; Rom 12:20). The coals then would be an implied comparison with a searing conscience.

[25:22]  ² sn The second consequence of treating enemies with kindness is that the Lord will reward the act. The fact that this is promised shows that the instruction here belongs to the religious traditions of Israel.

[5:44]  ³ tc Most mss ([D] L [W] Θ Ë¹³ 33 Ï lat) read “bless those who curse you, do good to those who hate you, and pray for those who mistreat you,” before “those who persecute you.” But this is surely a motivated reading, importing the longer form of this aphorism from Luke 6:27-28. The shorter text is found in א B ˹ pc sa, as well as several fathers and versional witnesses.
