Rashi
ויקרא לה נבח AND HE CALLED IT NOBAH — The word לה has no Mappik in the ה (as the word לָהּ "to it", usually has). Now I have seen the following in the work of R. Moses the Preacher: Because this name did not remain permanently to it, therefore the letter ה is weak (without a Mappik), — the implication of his explanation being that it (the word לה) is the same as לא “not”. But I wonder what explanation he will give of the two words similar to it, (Ruth 2:14): “And Boaz said לָה", and (Zechariah 5:11): “to build a house לָה”.
Bartenura
"He called it Nobach": The "hey" is not omitted, etc., until "and I am amazed what [the verse] would mean with the two words 'to Boaz' to build a house for her." It seems that Rashi did not notice what is written in the Midrash regarding these two words "to Boaz." The Midrash interprets that it was not said directly to her but through a messenger, to build a house for her. It is interpreted to mean that she has no house, meaning it has no lasting foundation, as falsehood and flattery have no standing. There, in Zechariah, the verse speaks of flattery.
Rabbeinu Bahya
ויקרא לה נבח בשמו, “He called it (the district) Novach just like himself.” The letter ה in the word לה is “weak,” i.e. without the customary dagesh. Ruth Rabbah 5,5 claims that the reason is that this name did not endure, i.e. the word is almost equivalent to having been spelled לא, “not.” We find other examples of the same defective spelling in Zecharyah 5,11: לבנות לה בית בארץ שנער, “to build a house for her (it) in the land of Shinar.” The subject there is the prophet being shown a measuring device known as eyfah which the angel transported away and the prophet wanted to know its significance. The prophet is informed that those who remain in Babylonia although the Temple was being reconstructed in Jerusalem would not have much of a future, as there is no future for untruth. The missing dagesh in the word לה in that verse alludes to the transience of people who decided to remain in a kingdom built on lies. Solomon expressed himself similarly when speaking about lies in Proverbs 12,19: “Truthful lips will be established forever; but a lying tongue endures only for a moment.” They will soon be tested and found to be lies. This is why man must love truth and hate lies. This is also what Zecharyah 8,19 said: “Love truth and peace!”
