A.T. Robertson Commentary Romans 11:5

"Even so then at this present time also there is a remnant according to the election of grace." — Romans 11:5 (ASV)

Remnant (λιμμα). Old word, but only here in N.T., but in papyri also and with this spelling rather than λειμμα. From λειπω, to leave.

According to the election of grace (κατ' εκλογην χαριτος). As in 9:6-13. The election is all of God. Verse 6 explains it further.
