First Option - First Reading: Hebrews 3:7-14


7 Therefore, as the Holy Spirit says, "Today, when you hear his voice,
8 do not harden your hearts as in the rebellion, on the day of testing in the wilderness,
9 where your fathers put me to the test and saw my works for forty years.
10 Therefore I was provoked with that generation, and said, `They always go astray in their hearts; they have not known my ways.'
11 As I swore in my wrath, `They shall never enter my rest.'"
12 Take care, brethren, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God.
13 But exhort one another every day, as long as it is called "today, " that none of you may be hardened by the deceitfulness of sin.
14 For we share in Christ, if only we hold our first confidence firm to the end,

Second Option - Responsorial Psalm: Psalms 16:1-2, 5, 7-8, 11


1 Preserve me, O God, for in thee I take refuge.
2 I say to the LORD, "Thou art my Lord; I have no good apart from thee."
5 The LORD is my chosen portion and my cup; thou holdest my lot.
7 I bless the LORD who gives me counsel; in the night also my heart instructs me.
8 I keep the LORD always before me; because he is at my right hand, I shall not be moved.
11 Thou dost show me the path of life; in thy presence there is fulness of joy, in thy right hand are pleasures for evermore.

First Option - Responsorial Psalm: Psalms 95:6-11


6 O come, let us worship and bow down, let us kneel before the LORD, our Maker!
7 For he is our God, and we are the people of his pasture, and the sheep of his hand. O that today you would hearken to his voice!
8 Harden not your hearts, as at Mer'ibah, as on the day at Massah in the wilderness,
9 when your fathers tested me, and put me to the proof, though they had seen my work.
10 For forty years I loathed that generation and said, "They are a people who err in heart, and they do not regard my ways."
11 Therefore I swore in my anger that they should not enter my rest.
