כִּֽי־יַעֲקֹ֗ב בָּחַ֣ר ל֣וֹ יָ֑הּ יִ֝שְׂרָאֵ֗ל לִסְגֻלָּתֽוֹ׃
Sapagkat pinili ng Walang-Hanggan si Jacob para sa Kanyang sarili, ang Israel bilang Kanyang mahalagang kayamanan.
Rashi
My chosen one Israel is called ‘My chosen one’ ([mss.:] His chosen one) (Ps. 135:4) “For the Eternal chose Jacob for Himself.” Scripture states also (infra 45:4): “For the sake of My servant Jacob and Israel My chosen one.”
Rambam
Jerusalem is called an inheritance for bringing its sanctity and establishing it forever. Regarding Jerusalem, the prophet said, "His inheritance shall not be forsaken" (Joel 3:20). At first, it is mentioned that God chose Jerusalem for His divine presence and chose Israel as His treasured nation. Afterwards, it is stated that God will watch over this people whom He has chosen in that place, as it is also said, "For the Lord has chosen Zion" (Psalms 132:13), "For the Lord has chosen Jacob" (Psalms 135:4). "For the Lord will not forsake His people" (1 Samuel 12:22). The greatness of Jerusalem is further explained, and it is said, "This is My resting place forever" (Psalms 132:14). The reference to "within the curtains" and "within the walls of the sanctuary" is explained as I have clarified on numerous occasions.
Or HaChaim
The Torah goes on וממדבר מתנה, "and from the wilderness to Matanah." This is a hint that whatever Torah-scholarship we acquire is due only to our first making ourselves like a wilderness, as we explained on Exodus 19,2 on the words "they camped in the desert." Torah can be acquired only by men who first train themselves to be humble. The Torah goes on in verse 19 וממתנה נחליאל, "and from Matanah to Nachliel." This is an allusion to the fact that G'd inherited us as it were by means of the Torah which He gave to us. This is spelled out in Deut. 32,9 יעקב חבל נחלתו. The words also mean that G'd chose only us as we know from Psalms 135,4: "for the Lord has chosen Jacob for Himself, Israel as His treasured possession." He even left His abode in heaven and took up residence amongst us.
