[Pro 27:1, 5-7, 12, 14-15, 17 KJV]
1 Boast not thyself of to morrow; for thou knowest not what a day may bring forth. …
*This reminded me of James 4.
[Jas 4:13-15 KJV] 13 Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain: 14 Whereas ye know not what [shall be] on the morrow. For what [is] your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. 15 For that ye [ought] to say, If the Lord will, we shall live, and do this, or that.
Pro 27:5 KJV Open rebuke [is] better than secret love.
6 Faithful [are] the wounds of a friend; but the kisses of an enemy [are] deceitful.
7 The full soul loatheth an honeycomb; but to the hungry soul every bitter thing is sweet.
... 12 A prudent [man] foreseeth the evil, [and] hideth himself; [but] the simple pass on, [and] are punished.
... 14 He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.
15 A continual dropping in a very rainy day and a contentious woman are alike.
... 17 Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.
[Pro 28:5-6, 9-10, 13, 18, 23, 25-26 KJV] 5 Evil men understand not judgment: but they that seek the LORD understand all [things].
6 Better [is] the poor that walketh in his uprightness, than [he that is] perverse [in his] ways, though he [be] rich.
... 9 He that turneth away his ear from hearing the law, even his prayer [shall be] abomination.
10 Whoso causeth the righteous to go astray in an evil way, he shall fall himself into his own pit: but the upright shall have good [things] in possession.
... 13 He that covereth his sins shall not prosper: but whoso confesseth and forsaketh [them] shall have mercy.
... 18 Whoso walketh uprightly shall be saved: but [he that is] perverse [in his] ways shall fall at once.
... 23 He that rebuketh a man afterwards shall find more favour than he that flattereth with the tongue.
... 25 He that is of a proud heart stirreth up strife: but he that putteth his trust in the LORD shall be made fat. 26 He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
