Take care, brethren, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God.
 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.
 For we share in Christ, if only we hold our first confidence firm to the end,
 while it is said, “Today, when you hear his voice,
do not harden your hearts as in the rebellion.”
 Who were they that heard and yet were rebellious? Was it not all those who left Egypt under the leadership of Moses?
 And with whom was he provoked forty years? Was it not with those who sinned, whose bodies fell in the wilderness?
 And to whom did he swear that they should never enter his rest, but to those who were disobedient?
 So we see that they were unable to enter because of unbelief.
 Therefore, while the promise of entering his rest remains, let us fear lest any of you be judged to have failed to reach it.
 For good news came to us just as to them; but the message which they heard did not benefit them, because it did not meet with faith in the hearers.
 For we who have believed enter that rest, as he has said, “As I swore in my wrath,
`They shall never enter my rest,'”
although his works were finished from the foundation of the world.
 For he has somewhere spoken of the seventh day in this way, “And God rested on the seventh day from all his works.”
 And again in this place he said, “They shall never enter my rest.”
 Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience,
 again he sets a certain day, “Today,” saying through David so long afterward, in the words already quoted, “Today, when you hear his voice,
do not harden your hearts.”
 For if Joshua had given them rest, God would not speak later of another day.
 So then, there remains a sabbath rest for the people of God;
 for whoever enters God’s rest also ceases from his labors as God did from his.
 And he told them a parable, to the effect that they ought always to pray and not lose heart.
 He said, “In a certain city there was a judge who neither feared God nor regarded man;
 and there was a widow in that city who kept coming to him and saying, `Vindicate me against my adversary.’
 For a while he refused; but afterward he said to himself, `Though I neither fear God nor regard man,
 yet because this widow bothers me, I will vindicate her, or she will wear me out by her continual coming.'”
 And the Lord said, “Hear what the unrighteous judge says.
 And will not God vindicate his elect, who cry to him day and night? Will he delay long over them?
 I tell you, he will vindicate them speedily. Nevertheless, when the Son of man comes, will he find faith on earth?”
