^12-15 You should therefore be most careful, my brothers, that there should not be in any of you that wickedness of heart which refuses to trust, and deserts the cause of the living God. Help each other to stand firm in the faith every day, while it is still called “today”, and beware that none of you becomes deaf and blind to God through the delusive glamour of sin. For we continue to share in all that Christ has for us so long as we steadily maintain until the end the trust with which we began. These words are still being said for our ears to hear: ‘Today, if you will hear his voice, do not harden your hearts as in the rebellion’.

^16-18 For who was it who heard the Word of God and yet provoked his indignation? Was is not all who were rescued from slavery in Egypt under the leadership of Moses? And who was it with whom God was displeased for forty long years? Was it not those who, after all their hearing of God’s Word, fell into sin, and left their bones in the desert? And to whom did God swear that they should never enter his rest? Was it not these very men who refused to trust him?
