2 Kings 8:13

And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.

And the Lord said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, anoint Hazael to be king over Syria:

And he bowed himself, and said, What is thy servant, that thou shouldest look upon such a dead dog as I am?

And Elisha said unto him, Go, say unto him, Thou mayest certainly recover: howbeit the Lord hath shewed me that he shall surely die.

Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.

Woe to them that devise iniquity, and work evil upon their beds! when the morning is light, they practise it, because it is in the power of their hand.

For dogs have compassed me: the assembly of the wicked have inclosed me: they pierced my hands and my feet.

Deliver my soul from the sword; my darling from the power of the dog.

His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber. Yea, they are greedy dogs which can never have enough, and they are shepherds that cannot understand: they all look to their own way, every one for his gain, from his quarter.

The heart is deceitful above all things, and desperately wicked: who can know it?

Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended. Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice. Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.

Beware of dogs, beware of evil workers, beware of the concision.

For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
