General Information:

This prophetic quotation comes from a Psalm of King David.

the one who sanctifies

"the one who makes others holy" or "the one who makes others pure from sin"

This can be stated in active form. AT: "those whom he makes holy" or "those whom he makes pure from sin" (See: rc://en/ta/man/translate/figs-activepassive)

Who that source is can be stated clearly. AT: "have one source, God himself" or "have the same Father" (See: rc://en/ta/man/translate/figs-explicit)

"Jesus is not ashamed"

This double negative means that he will claim them as his brothers. AT: "is pleased to call them his brothers" (See: rc://en/ta/man/translate/figs-doublenegatives)

Here this refers to all who have believed in Jesus, including both men and women. (See: rc://en/ta/man/translate/figs-gendernotations)
