יְהוָ֤ה ׀ שֹׁ֘מֵ֤ר אֶת־גֵּרִ֗ים יָת֣וֹם וְאַלְמָנָ֣ה יְעוֹדֵ֑ד וְדֶ֖רֶךְ רְשָׁעִ֣ים יְעַוֵּֽת׃
Iniingatan ng Walang-Hanggan ang mga dayuhan; pinalalakas Niya ang ulila at ang balo, ngunit binabaluktot Niya ang landas ng masasama.
Radak
ה' שומר את גרים. "The Lord preserves the strangers (or the converts).": The stranger (or the convert), the orphan, and the widow are weak because they have no helper, and He guards them. Therefore, the Torah warns about them in several places, and the Lord protects them. Similarly, He guards Israel, who were strangers among the nations and weak like an orphan and a widow.
Ibn Ezra
"God guards converts" - Who have no aid as they are from another nation.
