Read Galatians 2:4 Using Other Translations
And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
Yet because of false brothers secretly brought in--who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery--
Even that question came up only because of some so-called believers there—false ones, really —who were secretly brought in. They sneaked in to spy on us and take away the freedom we have in Christ Jesus. They wanted to enslave us and force us to follow their Jewish regulations.
