TSK · Ecclesiastes 10:12

David said to him, "Your blood be on your head; for your mouth has testified against you, saying, 'I have slain Yahweh's anointed.'"

Behold, you have instructed many, you have strengthened the weak hands.

The mouth of the righteous talks of wisdom. His tongue speaks justice.

Their own tongues shall ruin them. All who see them will shake their heads.

As for the head of those who surround me, let the mischief of their own lips cover them.

One winking with the eye causes sorrow, but a chattering fool will fall.

The tongue of the righteous is like choice silver. The heart of the wicked is of little worth.

The lips of the righteous know what is acceptable, but the mouth of the wicked is perverse.

There is one who speaks rashly like the piercing of a sword, but the tongue of the wise heals.

Joy comes to a man with the reply of his mouth. How good is a word at the right time!

A fool's lips come into strife, and his mouth invites beatings.

He who loves purity of heart and speaks gracefully is the king's friend.

A word fitly spoken is like apples of gold in settings of silver.

She opens her mouth with wisdom. Faithful instruction is on her tongue.

Don't allow your mouth to lead you into sin. Don't protest before the messenger that this was a mistake. Why should God be angry at your voice, and destroy the work of your hands?

All testified about him, and wondered at the gracious words which proceeded out of his mouth, and they said, "Isn't this Joseph's son?"

Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear.
