A.T. Robertson Commentary Romans 9:27

"And Isaiah crieth concerning Israel, If the number of the children of Israel be as the sand of the sea, it is the remnant that shall be saved:" — Romans 9:27 (ASV)

Isaiah (Εσαιας). Shortened quotation from Isa 10:22 (LXX).

It is the remnant that shall be saved (το υπολειμμα σωθησετα). First future passive of σωζω. Literally, "the remnant will be saved." Late word from υπολειπω, to leave behind (11:3), here only in N.T. Textus Receptus has καταλειμμα, but Aleph A B have υπολειμμα. Isaiah cries in anguish over the outlook for Israel, but sees hope for the remnant.
