forbidding us to speak to the Gentiles that they may be saved; to fill up their sins always. But wrath has come on them to the uttermost.
Fill up their sins -- to fill up the measure of their sins. cf. Genesis 15:16, Persecution were heaping sin upon sin. AS thou the bowl of God’s wrath against them was filling up. (God seems to be patient with sins, until one’s sins "fill up".)
