@DoubleAA it clears up some apparent misconceptions in the question. The question is unclear and should probably be closed. If it's clarified, it'll be easier to make a case for deleting this answer.

Tonight is the 36th Night of the Omer.

@IsaacMoses How is the question unclear? Whatever misconceptions in clears up are side points at best and don't affect the actual question.

Today I (and, I assume, most or all of us) heard what is possibly my favorite haftara.

Um, most or all of us outside of Israel, that is.

If we're allowed to pick favorites among people in Tanach, mine is probably Yirmiya.

I don't want to know what that says about me.

@msh210 I get very excited about this one, too. Signal. Looong position.

How does one vocalize the prefix "של-"? I see שֶׁלִּשְׁלֹמֹ֔ה, שֶׁלַּפֶּסַח and שׁלְּאַהֲרֹן. It may be that the niqud in my last two examples are dependent on the rabbinic vocalization tradition (cf. the last link) and should thus not be taking as biblical vocalization.

If so, should של- be vocalized as שֶלִּ- in all cases of biblical Hebrew?

Is this question even answerable, given the paucity of examples in Tanakh?

(Sorry, mistake: not last two examples, but first and last examples)

I note MS Kaufmann A50 has שֶׁלַּפֶּסַח (Mishna Maʿaser Sheni 5.6)

and שֶלַּשַּׁבָּתֿ (Mishna Shabbat 15.3)

@DoubleAA It doesn't explain the inconsistent vocalization in MS.

I should say, apparent inconsistency

@msh210 possibly my favorite (if we're allowed to have favorites) is the haftarah for Ki Tisa. I just love the interplay in that conflict!

Tonight will be/is the 37th Night of the Omer.
