וְנָתַ֣ן אַרְצָ֣ם לְנַחֲלָ֑ה כִּ֖י לְעוֹלָ֣ם חַסְדּֽוֹ׃
Dan memberikan negeri mereka menjadi milik pusaka, sebab kasih setia-Nya untuk selama-lamanya.
Midrash BeChiddush
וְנָתַ֣ן אַרְצָ֣ם לְנַחֲלָ֑ה “God gave their land as a heritage” (Ps. 136:21) refers to Isaac, for the land was given to him as an inheritance to be mainly for him and his offspring, the seed of Abraham.
Rashi
ימינך ה' נאדרי בכח THY RIGHT HAND, O LORD, IS GLORIOUS IN POWER to deliver Israel, and thy second right hand dashes the enemy in pieces. But it seems to me that if we have to take it in the sense: Thy right hand is glorious to save, thy right hand dashes in pieces etc. the explanation is that the self-same right hand itself dashes the enemy in pieces, something which it is impossible for a human being — to do two actions with one hand. But the literal sense of the text is: “Thy right hand, that is glorious in power — what does it do?” — “Thy right hand, O Lord, dashes the enemy in pieces”. There are many Scriptural verses exactly in this poetical form, e. g., (Psalms 92:10) “For, behold, thine enemies, O Lord, for behold, thine enemies shall perish” and others similar.
