The deceitful kiss of an enemy: Matthew 26:48-50 Now he that betrayed him gave them a sign, saying, Whomsoever I shall kiss, that same is he: hold him fast. [49] And forthwith he came to Jesus, and said, Hail, master; and kissed him. [50] And Jesus said unto him, Friend, wherefore art thou come? Then came they, and laid hands on Jesus, and took him.
Proverbs 27:6
[6] Faithful are the wounds of a friend;
but the kisses of an enemy are deceitful.
Zechariah 13:6-7[6] And one shall say unto him, What are these wounds in thine hands? Then he shall answer, Those with which I was wounded in the house of my friends. [7] Awake, O sword, against my shepherd, and against the man that is my fellow, saith the Lord of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn mine hand upon the little ones.
What are these wounds in thine hands? "Those with which I was wounded in the house of my friends."
The faithful wounds of a friend: Romans 5:7-10 For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. [8] But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. [9] Much more then, being now justified by his blood, we shall be saved from wrath through him. [10] For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
