The ‘pen’ which he was in was Judah.
Matthew 10:
[1] And when he had called unto him his twelve disciples, he gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease.
[2] Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother;
[3] Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus;
[4] Simon the Canaanite, and Judas Iscariot, who also betrayed him.
[5] These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
[6] But go rather to the lost sheep of the house of Israel.
Matthew 15:
[22] And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou Son of David; my daughter is grievously vexed with a devil.
[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 am not sent but unto the lost sheep of the house of Israel.
You are making it sound like Irishmen cannot be Yeshua’s sheep.
