זֶ֚רַע יִשְׂרָאֵ֣ל עַבְדּ֔וֹ בְּנֵ֥י יַעֲקֹ֖ב בְּחִירָֽיו׃
O ihr Samen Israels, sein Knecht, ihr Kinder Jakobs, seine Auserwählten.
Radak on I Chronicles
The seed of Israel His servant In the Book of Psalms [it is written]: “the seed of Abraham His servant,” and it says here, “The seed of Israel His servant,” because the meaning of “the seed of Abraham,” which is written there, refers to the seed of Israel, because Abraham had other seed, but the seed of Israel is exclusively for us; and when it says, “the seed of Abraham,” it means the seed of Israel.
