John 10:14
I am the good shepherd, and know my sheep, and am known of mine.

John 5:24-25
Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
[25] Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.

Isaiah 40:11
He shall feed his flock like a shepherd: he shall gather the lambs with his arm, and carry them in his bosom, and shall gently lead those that are with young.

Luke 15:3-10
And he spake this parable unto them, saying,
[4] What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it?
[5] And when he hath found it, he layeth it on his shoulders, rejoicing.
[6] And when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost.
[7] I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
[8] Either what woman having ten pieces of silver, if she lose one piece, doth not light a candle, and sweep the house, and seek diligently till she find it?
[9] And when she hath found it, she calleth her friends and her neighbours together, saying, Rejoice with me; for I have found the piece which I had lost.
[10] Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth.

So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
[16] He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.
[17] He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.

Acts 20:28-29
Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
[29] For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.

Matthew 7:15-21
Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
[16] Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
[17] Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
[18] A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
[19] Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
[20] Wherefore by their fruits ye shall know them.
[21] Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.

John 7:17-18
If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
[18] He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.

1 Peter 4:11
If any man speak, let him speak as the oracles of God; if any man minister, let him do it as of the ability which God giveth: that God in all things may be glorified through Jesus Christ, to whom be praise and dominion for ever and ever. Amen.

Isaiah 8:20
To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.

Proverbs 6:23
For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:

1 Timothy 6:3-5
If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;
[4] He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings,
[5] Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.

Psalm 23:1-6
The LORD is my shepherd; I shall not want.
[2] He maketh me to lie down in green pastures: he leadeth me beside the still waters.
[3] He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake.
[4] Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
[5] Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
[6] Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever.
