So then, ¹  whenever we have an opportunity, let us do good to all people, and especially to those who belong to the family of faith. ² 

Now this matter arose ¹  because of the false brothers with false pretenses ²  who slipped in unnoticed to spy on ³  our freedom that we have in Christ Jesus, to make us slaves. ⁴
