Mat 22:36 "Teacher, which is the great commandment in the Law?"

Mat 25:31 But when the Son of man shall come in his glory, and all the angels with him, then shall he sit on the throne of his glory:
Mat 25:32 and before him shall be gathered all the nations: and he shall separate them one from another, as the shepherd separateth the sheep from the goats;

Mat 25:34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
Mat 25:35 for I was hungry, and ye gave me to eat; I was thirsty, and ye gave me drink; I was a stranger, and ye took me in;
Mat 25:36 naked, and ye clothed me; I was sick, and ye visited me; I was in prison, and ye came unto me.

Mat 25:38 And when saw we thee a stranger, and took thee in? or naked, and clothed thee?

Mat 25:42 for I was hungry, and ye did not give me to eat; I was thirsty, and ye gave me no drink;
Mat 25:43 I was a stranger, and ye took me not in; naked, and ye clothed me not; sick, and in prison, and ye visited me not.
Mat 25:44 Then shall they also answer, saying, Lord, when saw we thee hungry, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
