shall
Matthew 7:20
Wherefore by their fruits ye shall know them.
Matthew 12:33
Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.
2 Peter 2:10-18
10
But chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous are they, selfwilled, they are not afraid to speak evil of dignities.
11
Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord.
12
But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;
13
And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you;
14
Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
15
Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness;
16
But was rebuked for his iniquity: the dumb ass speaking with man's voice forbad the madness of the prophet.
17
These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.
18
For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error.
Jude 1:10-19
10
But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.
11
Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core.
12
These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;
13
Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
14
And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
15
To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him.
16
These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage.
17
But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
18
How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
19
These be they who separate themselves, sensual, having not the Spirit.
Do
Luke 6:43-45
43
For a good tree bringeth not forth corrupt fruit; neither doth a corrupt tree bring forth good fruit.
44
For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.
45
A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
James 3:12
Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
