Hebrews 3.5-11, 17-19 (Epistle)
5And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;
6But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
7Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,
8Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:
9When your fathers tempted me, proved me, and saw my works forty years.
10Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways.
11So I sware in my wrath, They shall not enter into my rest.)
17But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness?
18And to whom sware he that they should not enter into his rest, but to them that believed not?
19So we see that they could not enter in because of unbelief.
Mark 8.11-21 (Gospel)
11And the Pharisees came forth, and began to question with him, seeking of him a sign from heaven, tempting him.
12And he sighed deeply in his spirit, and saith, Why doth this generation seek after a sign? verily I say unto you, There shall no sign be given unto this generation.
13And he left them, and entering into the ship again departed to the other side.
14Now the disciples had forgotten to take bread, neither had they in the ship with them more than one loaf.
15And he charged them, saying, Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod.
16And they reasoned among themselves, saying, It is because we have no bread.
17And when Jesus knew it, he saith unto them, Why reason ye, because ye have no bread? perceive ye not yet, neither understand? have ye your heart yet hardened?
18Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?
19When I brake the five loaves among five thousand, how many baskets full of fragments took ye up? They say unto him, Twelve.
20And when the seven among four thousand, how many baskets full of fragments took ye up? And they said, Seven.
21And he said unto them, How is it that ye do not understand?
