Should the name Bas Sheva be written as one or two words in a bill of divorce?
On Daf 22a it says that R. Yehudah in the name of Rav taught on the posuk in Melachim Ⅰ 1:15 “And Bas Sheva went in to the king, to the chamber” that on that occasion Bas Sheva wiped herself with thirteen cloths. Rashi explains that he means that she had relations with the king thirteen times and wiped herself each time. Rashi futher explains that he learned this from the fact that there are thirteen words in this posuk - ותבא בת שבע אל המלך החדרה והמלך זקן מאד ואבישג השונמית משרת את המלך .
Behold, from here it is clear that the name בת שבע must be written in a bill of divorce as one word and not as two words, because if we say that name consists of two words there would be fourteen words in this posuk!
How many times does the word סוד appear in Tanach?
On Daf 38a the gemora teaches that נכנס יין יצא סוד - when wine enters secrets emerge.
Behold, the word סוד appears in only three places in the Tanach:
סוד ה' ליראיו (Tehillim 25:14)
ואת ישרים סודו (Mishlei 3:32)
כי אם גלה סודו אל עבדיו הנביאים (Amos 3:7)
This is the allusion behind the teaching:
נכנס יין - ישרים,
יצא סוד - the three posukim which contain the word סוד in them emerge.
