Be careful that you don’t let anyone rob you through his philosophy and vain deceit, after the tradition of men, after the elements of the world, and not after Christ.
The whole law is fulfilled in one word, in this: “You shall love your neighbor as yourself.” But if you bite and devour one another, be careful that you don’t consume one another. But I say, walk by the Spirit, and you won’t fulfill the lust of the flesh.
He began to tell his disciples first of all, “Beware of the yeast of the Pharisees, which is hypocrisy. But there is nothing covered up, that will not be revealed, nor hidden, that will not be known. Therefore whatever you have said in the darkness will be heard in the light. What you have spoken in the ear in the inner rooms will be proclaimed on the housetops."
Beware! Keep yourselves from covetousness, for a man’s life doesn’t consist of the abundance of the things which he possesses.
He said to the disciples, “It is impossible that no occasions of stumbling should come, but woe to him through whom they come! It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, rather than that he should cause one of these little ones to stumble. Be careful."
“Heaven and earth will pass away, but my words will by no means pass away. So be careful, or your hearts will be loaded down with carousing, drunkenness, and cares of this life, and that day will come on you suddenly. For it will come like a snare on all those who dwell on the surface of all the earth. Therefore be watchful all the time, praying that you may be counted worthy to escape all these things that will happen, and to stand before the Son of Man.”
In his teaching he said to them, “Beware of the scribes, who like to walk in long robes, and to get greetings in the marketplaces, and the best seats in the synagogues, and the best places at feasts: those who devour widows’ houses, and for a pretense make long prayers. These will receive greater condemnation.”
A righteous person is cautious in friendship, but the way of the wicked leads them astray.
A simple man believes everything, but the prudent man carefully considers his ways.
I will be careful to live a blameless life. When will you come to me? I will walk within my house with a blameless heart.
1 Thessalonians 4:6.
No one should take advantage of and wrong a brother or sister in this matter; because the Lord is an avenger in all these things, as also we forewarned you and testified.
