[Pro 27:1 KJV] 1 Boast not thyself of to morrow; for thou knowest not what a day may bring forth.

[Isa 10:15 KJV] 15 Shall the axe boast itself against him that heweth therewith? [or] shall the saw magnify itself against him that shaketh it? as if the rod should shake [itself] against them that lift it up, [or] as if the staff should lift up [itself, as if it were] no wood.

[Psa 49:6-9 KJV] 6 They that trust in their wealth, and boast themselves in the multitude of their riches; 7 None [of them] can by any means redeem his brother, nor give to God a ransom for him: 8 (For the redemption of their soul [is] precious, and it ceaseth for ever:) 9 That he should still live for ever, [and] not see corruption.

[Psa 52:1 KJV] 1 [[To the chief Musician, Maschil, [A Psalm] of David, when Doeg the Edomite came and told Saul, and said unto him, David is come to the house of Ahimelech.]] Why boastest thou thyself in mischief, O mighty man? the goodness of God [endureth] continually.

[Psa 94:4 KJV] 4 [How long] shall they utter [and] speak hard things? [and] all the workers of iniquity boast themselves?

[Rom 3:27 KJV] 27 Where [is] boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.

[Rom 11:17-21 KJV] 17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree; 18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee. 19 Thou wilt say then, The branches were broken off, that I might be graffed in. 20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: 21 For if God spared not the natural branches, [take heed] lest he also spare not thee.

[1Co 1:17-31 KJV] 17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. 18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. 19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. 20 Where [is] the wise? where [is] the scribe? where [is] the disputer of this world? hath not God made foolish the wisdom of this world? 21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe. 22 For the Jews require a sign, and the Greeks seek after wisdom: 23 But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; 24 But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. 25 Because the foolishness of God is wiser than men; and the weakness of God is stronger than men. 26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, [are called]: 27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; 28 And base things of the world, and things which are despised, hath God chosen, [yea], and things which are not, to bring to nought things that are: 29 That no flesh should glory in his presence. 30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 31 That, according as it is written, He that glorieth, let him glory in the Lord.

[1Co 4:6-7 KJV] 6 And these things, brethren, I have in a figure transferred to myself and [to] Apollos for your sakes; that ye might learn in us not to think [of men] above that which is written, that no one of you be puffed up for one against another. 7 For who maketh thee to differ [from another]? and what hast thou that thou didst not receive? now if thou didst receive [it], why dost thou glory, as if thou hadst not received [it]?

[2Co 10:12-17 KJV] 12 For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise. 13 But we will not boast of things without [our] measure, but according to the measure of the rule which God hath distributed to us, a measure to reach even unto you. 14 For we stretch not ourselves beyond [our measure], as though we reached not unto you: for we are come as far as to you also in [preaching] the gospel of Christ: 15 Not boasting of things without [our] measure, [that is], of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly, 16 To preach the gospel in the [regions] beyond you, [and] not to boast in another man's line of things made ready to our hand. 17 But he that glorieth, let him glory in the Lord.

[Eph 2:8-10 KJV] 8 For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
