ישבתי [יֹשַׁבְתְּ֙] בַּלְּבָנ֔וֹן מקננתי [מְקֻנַּ֖נְתְּ] בָּֽאֲרָזִ֑ים מַה־נֵּחַנְתְּ֙ בְּבֹא־לָ֣ךְ חֲבָלִ֔ים חִ֖יל כַּיֹּלֵדָֽה׃
Ikaw na naninirahan sa Lebanon, na namumugad sa gitna ng mga sedro, anong lingap ang matatamo mo kapag dumating sa iyo ang mga hapdi, ang panginginig na gaya ng sa babaeng nanganganak!
Rashi
וְיֹלַדְתְּ בן AND THOU SHALT BEAR A SON — The word appears to be grammatically a combination of the perfect tense וְיָלַדְתְּ and the participle וְיֹלֶדֶת but it is similar in sense to וְיֹלֶדֶת (the participle); so, also, (Jeremiah 22:23) “O thou that dwellest יֹשַׁבְתְּ) in Lebanon, and art nestled (מְקֻנַּנְתְּ) in the cedars.”

As if it were written ויולדת... I.e., יוֹלֶדֶת, which is present tense. [Rashi is saying:] Do not be surprised by the שוא under the ת, for it is similar to (Yirmeyahu 22:23):יושבת בלבנון מקוננת בארזים, which also are present tense, and have a שוא under the ת.
