Genesis 32:6

Esau - cometh - and four hundred men with him - Jacob, conscious that he had injured his brother, was now apprehensive that he was coming with hostile intentions, and that he had every evil to fear from his displeasure. Conscience is a terrible accuser. It was a fine saying of a heathen,

Hic murus aheneus esto,

Nil conscire sibi, nulla pallescere culpa.

Hor. Ep., l. i., E. i., v. 60.

Be this thy brazen bulwark of defense,

Still to preserve thy conscious innocence,

Nor e'er turn pale with guilt.

Francis.

In other words, He that has a good conscience has a brazen wall for his defense; for a guilty conscience needs no accuser; sooner or later it will tell the truth, and not only make the man turn pale who has it, but also cause him to tremble even while his guilt is known only to himself and God.

It does not appear that Esau in this meeting had any hostile intention, but was really coming with a part of his servants or tribe to do his brother honor. If he had had any contrary intention, God had removed it; and the angelic host which Jacob met with before might have inspired him with sufficient confidence in God's protection. But we find that when he needed faith most, he appears to have derived but little benefit from its influence, partly from the sense he had of the injury he had done to his brother, and partly from not attending sufficiently to the assurance which God had given him of his gracious protection.

32:6 He cometh to meet thee, and four hundred men with him - He is now weary of waiting for the days of mourning for his father, and before those come resolves to slay his brother. Out he marches with four hundred men, probably such as used to hunt with him, armed no doubt, ready to execute the word of command.
