{If thou shalt confess} (ean homolog(8873)(8869)s). Third class
condition (ean and first aorist active subjunctive of
homologe(935c)). {With thy mouth Jesus as Lord} (en t(9369) stomati sou
Kurion I(8873)oun). This is the reading of nearly all the MSS. But B
71 Clem of Alex. read 	o r(886d)a en t(9369) stomati sou hoti Kurios
I(8873)ous (the word in thy mouth that Jesus is Lord). The idea is
the same, the confession of Jesus as Lord as in  1Co 12:3  Php
2:11 . No Jew would do this who had not really trusted Christ,
for Kurios in the LXX is used of God. No Gentile would do it
who had not ceased worshipping the emperor as Kurios. The word
Kurios was and is the touchstone of faith. {And shalt believe}
(kai pisteus(8869)s). Same construction. Faith precedes confession,
of course.
