Galatians 6

so
The word “so” here translates οὕτως (houtōs), which is an adverb for describing the manner in which something is done, sometimes also translated with “thus” (e.g., Luke 24:46), “in this way” (e.g., Matt 3:15), or “in such a way” (e.g., Matt 5:16). Here, Paul emphasizes that the way believers fulfill the law of Christ is by bearing one another’s burdens.

my own hand!
This verse is punctuated with an exclamation mark to bring out the proper emphasis as Paul in this verse is calling attention to his own writing. The imperative form of “See” (Ἴδετε; Idete) reinforces the idea that Paul is interjecting something here in emphatic fashion, and the punctuation in English helps to bring this out more clearly.

As many as…these are
The construction “As many as…these are” literally translates the Greek construction ὅσος…οὗτοι (hosos…houtoi) here. With this expression, Paul is equating the false teachers who want believers to be circumcised with simple externalists who just want to selfishly avoid suffering.

wanting
“Wanting” translates the Greek verb θέλω (thelō), which is a key term in Galatians that Paul uses to describe the false teachers and their desires, and to contrast them with his own. This theme appears throughout this epistle (1:7; 3:2; 4:9, 17, 20, 21; 6:13), and consistent translation with either “want” or “wish” helps the reader to pick up on what Paul is doing with his intentional wording. Here, the false teachers want to use the Galatians to puff themselves up, while Paul aims to call them back to the true Gospel.

may it never be
The exclamation, “May it never be!” represents the Greek construction μὴ γένοιτο (mē genoito), which is a strong way of expressing the desire that something never take place. Thus, other translations choose something like “God forbid!,” “By no means!,” or “Absolutely not!” to translate it. These all accurately convey the idea, but “May it never be!” is most literal to the Greek text because the verb used here comes from γίνομαι (ginomai) which is a state-of-being verb, negated and used in the optative mood, which communicates a strong desire that the action of the verb not take place. This expression is used by Paul 14 times in his writings (Rom 3:4, 6; 31; 6:2, 15; 7:7, 13; 9:14; 11:1, 11; 1 Cor 6:15; Gal 2:17; 3:21; here).

walk in step
“Walk in step” is from στοιχέω (stoicheō), which was used earlier in 5:25 to encourage that believers walk in conformity to the standard of living defined by the Spirit and His fruit in their life. Here, Paul uses it in similar fashion to encourag the Galatians to conform to the principles of boasting only in the cross of Christ and new creation that Christ brings about.

marks
The Greek term στίγμα (stigma) here is translated as “marks” rather than “brand-marks” to avoid over-translation. While the meaning of the term may include the idea of being branded, branding is just one of several ways someone could be “marked” (e.g., tatoos, scars, etc.). Thus, “marks” keeps the translation more general where the origial text does not specify the exact kind of marks. By refering to these “marks of Jesus” on his body, Paul is likely calling attention to the scars he had ammassed in his ministry of the gospel for Jesus—marks demonstrating his sincerity and sacrifice as well as authenticating his genuine belonging to Jesus.
