Are there numerical puns in the bible? Well, why don't you consider this story?
What does Abraham mean by seven ewe lambs?
28 And Abraham set seven ewe lambs of the flock by themselves.
29 And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?
30 And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.
31 Wherefore he called that place Beersheba; because they sware both of them,
32 Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines.
— Genesis 21:28-32
Why "wherefore" (v31)? In Hebrew, "beer" means well (Genesis 16:14), and "sheba" means to sware. Hence, Beersheba (v31) is named after the well (v30) and the covenant (v32) they swore: "because they sware both of them" (v31).
What about the seven ewe lambs? Plainly from the passage, they are a witness to Abraham that he has digged the well.
But there's something more going on here, because it's not really explained why ewe lambs, and why there are seven of them. A clue we have is that seven in Hebrew is "sheba".
"Sheba" meaning seven is a pun on "sheba" meaning to sware.
Also think about what a "she-baa" is in English...A child could tell you it's a female sheep. We have seven ("sheba") she-baas.
There's more depth to the story than this, but the puns seem to be there and seem to be multilingual. Having said that, this isn't obviously a numerical pun but a pun involving a number.
