If you have been foolish in exalting yourself,Or if you have devised evil, put your hand on your mouth.
For as the churning of milk produces butter,And wringing the nose produces blood,So the forcing of wrath produces strife.
Proverbs 30:32–33 · NKJVPart of Put Your Hand On Your Mouth, Proverbs 30:32–33.
Quick answer
The chapter's only direct command, and it is addressed to someone already in the wrong: if you have been lifting yourself up, or plotting, stop talking. The hand is a physical instruction.

The two verses are one saying, and the second is useless without the first. Verse 32 gives an instruction and verse 33 gives the physics behind it, joined by for.
The instruction assumes a person who has already gone wrong. Not "do not exalt yourself," which is what the reader expects and what 25:6 actually says, but if you have. Something has happened, and the saying meets the person afterward. What it asks for is not an apology, an explanation, or a defence. It is a hand over a mouth, a gesture Job makes when he finally stops arguing, and it is the last picture in Agur's collection.
Verse 33 explains why nothing else will do, and its argument is built on one word used three times. מִיץ, pressing or squeezing, opens all three lines. Milk pressed becomes butter, which is a good outcome. A nose pressed produces blood, which is not. Anger pressed produces strife, and there is the third. The mechanism is identical in all three; only the material changes.
And the Hebrew tightens it further, because the second and third lines use the same noun. אַף is the word for a nose and, in its dual form, the ordinary word for anger. The NKJV prints "nose" in one line and "wrath" in the next, and both are the same word. Squeeze a nose, squeeze a temper: in Hebrew that is one sentence saying itself twice, and the blood in the middle line is the warning about the third.
What it does not mean
This is not a verse for telling somebody else to be quiet. Its grammar is second person and its condition is personal: if you have been foolish, if you have devised evil. It hands the reader a hand and their own mouth, and it hands nobody a hand for anyone else's. Used to silence a person raising a problem, it reverses completely, since the one thing the saying forbids is escalating what is already under pressure.
Nor is it a rule that anger must never be expressed. What verse 33 describes is pressing, forcing, working something until it yields, and the difference between speaking while angry and forcing an outcome while angry is the whole distinction. 29:11 made it too: the contrast is between discharge and governance, never between feeling and numbness.
From this side of the cross
The words of Agur end where they began. A man who opened by saying he was more stupid than any man and had never learned wisdom closes by putting his hand over his mouth, and the whole collection turns out to be a single consistent posture. He never claims to have arrived. He never resolves his six questions. The one thing he holds is what he said in verse 5: God's word came out of the fire proven, and it is a shield to whoever trusts it.
That is a good place for the book's strangest voice to leave the reader. Not with a technique, and not with a standard to meet, but with a closed mouth and something outside himself to stand behind.
What this verse contributes
the command, and its unusual timing. It arrives after the failure rather than before it, which is what makes it usable by the person who most needs it.
The other half
The reason, in three pictures. Press milk and you get butter, press a nose and you get blood, press anger and you get a fight. Pressure produces, every time, and what it produces depends on what you pressed.
