If you won't read the "Old Testament" then you won't get it. So you think Peter is just foolhardy? Or the Lord Jesus Christ? I will give you the "New Testament" since you won't read the prophets. But first I will show you the standard. From Genesis.
Now the Lord had said to Abram:
“Get out of your country,
From your family
And from your father’s house,
To a land that I will show you.
2 I will make you a great nation;
I will bless you
And make your name great;
And you shall be a blessing.
3 I will bless those who bless you,
And I will curse him who curses you;
And in Matthew he said this.
22 And behold, a woman of Canaan came from that region and cried out to Him, saying, “Have mercy on me, O Lord, Son of David! My daughter is severely demon-possessed.”
23 But He answered her not a word.
And His disciples came and urged Him, saying, “Send her away, for she cries out after us.” 24 But He answered and said, “I was not sent except to the lost sheep of the house of Israel.”
25 Then she came and worshiped Him, saying, “Lord, help me!”
26 But He answered and said, “It is not good to take the children’s bread and throw it to the little dogs.”
She blessed Israel, and showing great allegiance to a duty (faith) and he blessed her. But not until after.
According to Luke, Peter stated what we are saying. Peter, full of the Holy Spirit. Leader of the Little Flock.
25 As Peter was coming in, Cornelius met him and fell down at his feet and worshiped him. 26 But Peter lifted him up, saying, “Stand up; I myself am also a man.” 27 And as he talked with him, he went in and found many who had come together. 28 Then he said to them, “You know how unlawful it is for a Jewish man to keep company with or go to one of another nation.
I would show you the "Old Testament", but you seem to not care about what Jesus taught. But there you have it.
