Jamieson, Fausset and Brown on Hebrews 11:7

7. warned of God--The same Greek, He 8:5, "admonished of God."

moved with fear--not mere slavish fear, but as in He 5:7; see on He 5:7; Greek, "reverential fear": opposed to the world's sneering disbelief of the revelation, and self-deceiving security. Join "by faith" with "prepared an ark" (1Pe 3:20).

by the which--faith.

condemned the world--For since he believed and was saved, so might they have believed and been saved, so that their condemnation by God is by his case shown to be just.

righteousness which is by faith--Greek, "according to faith." A Pauline thought. Noah is first called "righteous" in Ge 6:9. Christ calls Abel so, Mt 23:35. Compare as to Noah's righteousness, Eze 14:14, 20; 2Pe 2:5, "a preacher of righteousness." Paul here makes faith the principle and ground of his righteousness.

heir--the consequence of sonship which flows from faith.
