1 Samuel 3:15 - Wesley's Explanatory Notes

Doors — Altho' the tabernacle, whilst it was to be removed from place to place in the wilderness, had no doors, but consisted only of curtains, and had hangings before the entrance, instead of doors; yet when it was settled in one place, as now it was in Shiloh, it was enclosed within some solid building, which had doors and posts, and other parts belonging to it. Feared — The matter of the vision or revelation, partly from the reverence he bore to his person, to whom he was loth to be a messenger of such sad tidings; partly, lest if he had been hasty to utter it, Eli might think him guilty of arrogancy or secret complacency in his calamity.
