Jos 10:6-8, Mt 15:24-28

In the Old Testament, the Gibeonites asked Joshua to keep their people as slaves. (Joshua 9:9-11)

Joshua 9:9 And they said unto him, From a very far country thy servants are come because of the name of the Lord thy God: for we have heard the fame of him, and all that he did in Egypt, 10 And all that he did to the two kings of the Amorites, that were beyond Jordan, to Sihon king of Heshbon, and to Og king of Bashan, which was at Ashtaroth. 11 Wherefore our elders and all the inhabitants of our country spake to us, saying, Take victuals with you for the journey, and go to meet them, and say unto them, We are your servants: therefore now make ye a league with us.

In the Old Testament, when the Gibeonites were attacked by other tribes, Joshua rescued them. (Joshua 10:6-8)

Joshua 10:6 And the men of Gibeon sent unto Joshua to the camp to Gilgal, saying, Slack not thy hand from thy servants; come up to us quickly, and save us, and help us: for all the kings of the Amorites that dwell in the mountains are gathered together against us. 7 So Joshua ascended from Gilgal, he, and all the people of war with him, and all the mighty men of valour. 8 And the Lord said unto Joshua, Fear them not: for I have delivered them into thine hand; there shall not a man of them stand before thee.

When a Gentile woman asked her Jesus to heal her own daughter, Jesus healed her daughter. (Matthew 15:24-28)

Matthew 15:24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel. 25 Then came she and worshipped him, saying, Lord, help me. 26 But he answered and said, It is not meet to take the children's bread, and to cast it to dogs. 27 And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters' table. 28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.

As God and the Christ, Jesus was also gracious to the Gentiles.
