Mark 14:32 (KJV)

And Jesus saith unto him, Verily I say unto thee, That this day, even in this night, before the cock crow twice, thou shalt deny me thrice.

But he spake the more vehemently, If I should die with thee, I will not deny thee in any wise. Likewise also said they all.

And they came to a place which was named Gethsemane: and he saith to his disciples, Sit ye here, while I shall pray.

And he taketh with him Peter and James and John, and began to be sore amazed, and to be very heavy;

And saith unto them, My soul is exceeding sorrowful unto death: tarry ye here, and watch.
