Hebrews 10:24-25 (ESV)
And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.
Hebrews 6:13-18 (KJV)
For when God made promise to Abraham, because he could swear by no greater, he sware by himself, Saying, Surely blessing I will bless thee, and multiplying I will multiply thee. And so, after he had patiently endured, he obtained the promise. For men verily swear by the greater: and an oath for confirmation is for them an end of all strife. Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath: That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us.
Hebrews 12:22-29 (KJV)
But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven: Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven. And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: For our God is a consuming fire.
Hebrews 4:14-16 (KJV)
Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. For we have not an high priest which cannot be touched with the feeling of our infirmities; but was all points tempted like as we are, yet without sin. Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Hebrews 11:6 (KJV)
But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Hebrews 13:23-24 (NASB)
"Take notice that our brother Timothy has been released, with whom, if he comes soon, I will see you. Greet all of your leaders and all the saints. Those from Italy greet you."
Hebrews 13:22 (NASB)
"I urge you, brethren, bear with this word of exhortation, for I have written to you briefly."
"Do not speak within the hearing of a fool, for he will despise the wisdom of your words" (Proverbs 23:9)
Hebrews 13:20-21 (NASB)
"Now (may) the God of peace ... equip you in every good thing to do His will, working in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever. Amen"
