Surely
Surety, besides its use in "of a surety" appears, in the Old Testament to translate `arabh, "to be surety," and in Heb 7:22 for egguos, "guarantor," "giver of security." Modern English prefers "security," as does even the King James Version in Ac 17:9. "Suretiship" (the American Standard Revised Version "suretyship") in Proverbs 11:15 for taqa`, "to strike (hands)."
