I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naive. For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil.
From Proverbs 2:
My son, if you receive my words
and treasure up my commandments with you,
making your ear attentive to wisdom
and inclining your heart to understanding;
yes, if you call out for insight
and raise your voice for understanding,
if you seek it like silver
and search for it as for hidden treasures,
then you will understand the fear of the Lord
and find the knowledge of God.
For the Lord gives wisdom;
from his mouth come knowledge and understanding;
he stores up sound wisdom for the upright;
he is a shield to those who walk in integrity,
guarding the paths of justice
and watching over the way of his saints.
Then you will understand righteousness and justice
and equity, every good path;
for wisdom will come into your heart,
and knowledge will be pleasant to your soul;
discretion will watch over you,
understanding will guard you,
delivering you from the way of evil,
from men of perverted speech,
who forsake the paths of uprightness
to walk in the ways of darkness,
who rejoice in doing evil
and delight in the perverseness of evil,
men whose paths are crooked,
and who are devious in their ways.
So you will be delivered from the forbidden woman,
from the adulteress with her smooth words,
who forsakes the companion of her youth
and forgets the covenant of her God;
for her house sinks down to death,
and her paths to the departed;
none who go to her come back,
nor do they regain the paths of life.
From Proverbs 5:
My son, be attentive to my wisdom;
incline your ear to my understanding,
that you may keep discretion,
and your lips may guard knowledge.
For the lips of a forbidden woman drip honey,
and her speech is smoother than oil,
but in the end she is bitter as wormwood,
sharp as a two-edged sword.
From Proverbs 6:
My son, keep your father’s commandment,
and forsake not your mother’s teaching.
Bind them on your heart always;
tie them around your neck.
When you walk, they will lead you;
when you lie down, they will watch over you;
and when you awake, they will talk with you.
For the commandment is a lamp and the teaching a light,
and the reproofs of discipline are the way of life,
to preserve you from the evil woman,
from the smooth tongue of the adulteress.
From Proverbs 7:
Say to wisdom, “You are my sister,”
and call insight your intimate friend,
to keep you from the forbidden woman,
from the adulteress with her smooth words.
