Charles Ellicott Commentary Hebrews 11:2

"For therein the elders had witness borne to them." — Hebrews 11:2 (ASV)

For by it.—Better, For in it witness was borne to the elders. The connection seems to be this: Faith truly accomplishes all this; for it was in the exercise of such a faith that the elders gained the witness which the Scripture bears (see Hebrews 11:4-5, 39) to them and to their noble deeds. This verse, then, is added to confirm the first.
