“Yea, mine own familiar friend, in whom I trusted,
which did eat of my bread, has lifted up his heel against me.”
Jesus revealed that he himself was the one speaking those words through the prophet David, foretelling, a thousand years before it happened, that one of his disciples would betray him:
10. Jesus said to him, “He who has been washed needs only to wash his feet, but he is entirely clean.
11. (He knew who would betray him; this is why he said, “You are not all clean.”)
12. Then, when he had washed their feet, he put his garments back on, reclining again at the table, and said to them,
. . .
18. I know the ones I’ve chosen, but so that the Scripture might be fulfilled, it must be that ‘he who eats bread with me has lifted up his heel against me.’
When the Son of God in heaven made that statement through David, it was only part of what he said. Here is his statement, in context:
4. I said, Lord, be merciful unto me: heal my soul; for I have sinned against you.
5. Mine enemies speak evil of me, When shall he die, and his name perish?
. . .
8. “An evil disease”, say they, “cleaves fast unto him, and now that he lieth he shall rise up no more.”
9. Yea, mine own familiar friend, in whom I trusted, which did eat of my bread, hath lifted up his heel against me.
As a man, the Son of God felt sinful. He never sinned, but he felt the guilt and the shame of the sinful nature of the body of flesh he had come and taken on. Everyone in a fleshly body feels its sinfulness. Whenever you feel it, just follow the Son’s example and tell the Father about it. He will lift up your head and will see to it that you are not discouraged, just as He did Jesus. And afterward, you will glorify God again, just as Jesus did God:
11. By this I know that you favor me, because mine enemy does not triumph over me.
12. And as for me, you uphold me in mine integrity, and set me before your face for ever.
13. Blessed be the Lord God of Israel from everlasting, and to everlasting. Amen, and Amen.
