What is the correlation between the two halves of the Pasuk?
Ramban #1 (citing the Ibn Ezra): With reference to the future 1 - "You will lead with Your kindness (via the Pillars of Cloud and of Fire)... , You will lead them slowly (but surely) to the Your holy dwelling".
Seforno: The first half refers to the past - when, after taking them outside the border of Egypt to Succos, Hashem guided them in the desert (via the two Clouds). 2 Whereas the second half refers to the present - having led them slowly through the sea on dry land, He was now leading them 3 on the journey to His holy dwelling, to sanctify them there in His service.
Ramban #2: Having discussed the fate of the Egyptians (in the previous Pasuk), the Torah now relates how Hashem saved Yisrael with the Might of His Hand - on a journey towards His holy dwelling-place.
Hadar Zekenim and Rosh: "Nachisa ve'Chasdecha" is Tzedakah (Gemilus Chasadim). "Nehalta ve'Azcha" is Torah (Torah). "el Neve Kadshecha" is the Beis ha'Mikdash (Avodah). 4
As is the way of Pesukim regarding prophecy (Ibn Ezra). The Ibn Ezra himself presents an alternative explanation that is similar to that of the Seforno (Refer to 15:13:1:2).
Like a horse in the desert, to prevent them from stumbling (Seforno).
Targum Onkelos translates it as 'carrying them' (See Rashi), Targum Yonasan as 'inherited to them'.
Rosh: This alludes to three things on which the world stands (Avos 1:2).
What is the Pasuk referring to when it writes "Your holy dwelling-place"?
Rashbam: It refers to Eretz Cana'an.
