"I am the good shepherd; and I know My sheep, and am known by My own."

Ezekiel 34:11-12:
11‘For thus says the Lord God: “Indeed I Myself will search for My sheep and seek them out.
12 As a shepherd seeks out his flock on the day he is among his scattered sheep, so will I seek out My sheep and deliver them from all the places where they were scattered on a cloudy and dark day.

Jeremiah 23:1-2:
1 “Woe to the shepherds who are destroying and scattering the sheep of my pasture!” declares the Lord.
2 Therefore this is what the Lord, the God of Israel, says to the shepherds who tend my people: “Because you have scattered my flock and driven them away and have not bestowed care on them, I will bestow punishment on you for the evil you have done,” declares the Lord.
3 “I myself will gather the remnant of my flock out of all the countries where I have driven them and will bring them back to their pasture, where they will be fruitful and increase in number.

Matthew 9:36-38:
36 But when He saw the multitudes, He was moved with compassion for them, because they were weary and scattered, like sheep having no shepherd.
37 Then He said to His disciples, “The harvest truly is plentiful, but the laborers are few.
38 Therefore pray the Lord of the harvest to send out laborers into His harvest.”

Matthew 10:1-8:
1 And when He had called His twelve disciples to Him, He gave them power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease.
...
5 These twelve Jesus sent out and commanded them, saying: “Do not go into the way of the Gentiles, and do not enter a city of the Samaritans.
6 But go rather to the lost sheep of the house of Israel.
7 And as you go, preach, saying, ‘The kingdom of heaven is at hand.’
8 Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.

Isaiah 56:6-8:
6 “Also the sons of the foreigner
Who join themselves to the Lord, to serve Him,
And to love the name of the Lord, to be His servants—
Everyone who keeps from defiling the Sabbath,
And holds fast My covenant—
7 Even them I will bring to My holy mountain,
And make them joyful in My house of prayer.
Their burnt offerings and their sacrifices
Will be accepted on My altar;
For My house shall be called a house of prayer for all nations.”
8 The Lord God, who gathers the outcasts of Israel, says,
“Yet I will gather to him
Others besides those who are gathered to him.”

John 10:14-16:
14I am the good shepherd; and I know My sheep, and am known by My own.
15 As the Father knows Me, even so I know the Father; and I lay down My life for the sheep.
16 And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd.

John 10:27:
26 But you do not believe, because you are not of My sheep, as I said to you.
27 My sheep hear My voice, and I know them, and they follow Me.
28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.

John 10:30:
30 I and My Father are one.”
