notice Melchizedek was a believer of God not related to Abraham.
This is interesting since we have learned a bias toward the Law
Excellent point! Yes, this is interesting but nothing that's not been alluded to in other places in scripture:
16 And
other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice: and they shall become one flock, one shepherd. Jn 10
1 Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for
more are the children of the desolate than the children of the married wife, saith Jehovah. Isa 54 [ Galatians 4:26-27 ]
1 Now when Jesus was born in Bethlehem of Judaea in the days of Herod the king, behold,
Wise-men from the east came to Jerusalem, saying,
2 Where is he that is born King of the Jews? for we saw his star in the east, and are
come to worship him. Mt 2
25 But of a truth I say unto you,
There were many widows in Israel in the days of Elijah, when the heaven was shut up three years and six months, when there came a great famine over all the land;
26 and
unto none of them was Elijah sent, but only to Zarephath, in the land of Sidon, unto a woman that was a widow.
27 And
there were many lepers in Israel in the time of Elisha the prophet; and none of them was cleansed, but only Naaman the Syrian. Lu 4
8 And
the centurion answered and said, Lord,
I am not worthy that thou shouldest come under my roof; but only say the word, and my servant shall be healed.
9 For I also am a man under authority, having under myself soldiers: and I say to this one, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it.
10 And when Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you,
I have not found so great faith, no, not in Israel. Mt 8
22 And behold,
a Canaanitish woman came out from those borders, and cried, saying, Have mercy on me, O Lord, thou son of David; my daughter is grievously vexed with a demon.
23 But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us.
24 But he answered and said,
I was not sent but unto the lost sheep of the house of Israel.
25 But
she came and worshipped him, saying, Lord, help me.
26 And he answered and said, It is not meet to take the children`s bread and cast it to the dogs.
27 But she said, Yea, Lord: for even 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 done unto thee even as thou wilt. And her daughter was healed from that hour. Mt 15
9 After these things I saw, and behold,
a great multitude, which no man could number,
out of every nation and of all tribes and peoples and tongues, standing before the throne and before the Lamb, arrayed in white robes, and palms in their hands;
10 and
they cry with a great voice, saying, Salvation unto our God who sitteth on the throne, and unto the Lamb. Rev 7
(and I'm sure there's many more examples that could be found)
