Hebrews 3.5-11, 17-19 (Epistle)
5Moses indeed was faithful in all his house as a servant, for a testimony of those things which were afterward to be spoken,
6but Christ is faithful as a Son over his house. We are his house, if we hold fast our confidence and the glorying of our hope firm to the end.
7Therefore, even as the Holy Spirit says, “Today if you will hear his voice,
8don’t harden your hearts as in the rebellion, in the day of the trial in the wilderness,
9where your fathers tested me and tried me, and saw my deeds for forty years.
10Therefore I was displeased with that generation, and said, ‘They always err in their heart, but they didn’t know my ways.’
11As I swore in my wrath, ‘They will not enter into my rest.’”
17With whom was he displeased forty years? Wasn’t it with those who sinned, whose bodies fell in the wilderness?
18To whom did he swear that they wouldn’t enter into his rest, but to those who were disobedient?
19We see that they weren’t able to enter in because of unbelief.
Mark 8.11-21 (Gospel)
11The Pharisees came out and began to question him, seeking from him a sign from heaven and testing him.
12He sighed deeply in his spirit and said, “Why does this generation seek a sign? Most certainly I tell you, no sign will be given to this generation.”
13He left them, and again entering into the boat, departed to the other side.
14They forgot to take bread; and they didn’t have more than one loaf in the boat with them.
15He warned them, saying, “Take heed: beware of the yeast of the Pharisees and the yeast of Herod.”
16They reasoned with one another, saying, “It’s because we have no bread.”
17Jesus, perceiving it, said to them, “Why do you reason that it’s because you have no bread? Don’t you perceive yet or understand? Is your heart still hardened?
18Having eyes, don’t you see? Having ears, don’t you hear? Don’t you remember?
19When I broke the five loaves among the five thousand, how many baskets full of broken pieces did you take up?” They told him, “Twelve.”
20“When the seven loaves fed the four thousand, how many baskets full of broken pieces did you take up?” They told him, “Seven.”
21He asked them, “Don’t you understand yet?”
