Bite your tongue

HI, can you please help me find the meaning and orlgin of this phrase.

Bite your tongue. It means keep quiet. Don't say anything.

Can you tell us how this phrase originated?

It sounds very 'Bible or Shakespeare'. Can't find it in the Bible. It does come up in Shakespeare in King Henry IV:

So York must sit and fret and bite his tongue,
While his own lands are bargain'd for and sold.

Shakespeare was very fond of the word tongue; it appears hundreds of times in his plays. Incidentally, he never used the word Bible.

And the Bible never mentions Shakespeare.
