Brothers

See how you translated this in Galatians 1:2.

in human terms

"as a person" or "of things most people understand"

Now

This word shows that Paul has stated a general principle and is now beginning to introduce a specific case.

referring to many

"referring to many descendants"

to your descendant

The word "your" is singular and refers to a specific person, who is a particular descendant of Abraham (and that descendant is identified as "Christ"). (See: rc://en/ta/man/translate/figs-you)
