King James Dictionary [2]

MEAL, n.

1. A portion of food taken at one time a repast. It is customary in the U. States to eat three meals in a day. The principal meal of our ancestors was dinner, at noon. 2. A part a fragment in the word piece-meal.

MEAL, n. L. mola, mollis Eng.mellow.

1. The substance of edible grain ground to fine particles, and not bolted or sifted. Meal primarily includes the bran as well as the flour. Since bolting has been generally practiced, the word meal is not generally applied to the finer part, or flour, at least in the United States, though I believe it is sometimes so used. In New England, meal is now usually applied to ground maiz, whether bolted or unbolted, called Indian meal, or corn-meal. The words wheat-meal,and rye-meal are rarely used,though not wholly extinct and meal occurs also in oatmeal. 2. Flour the finer part of pulverized grain.

This sense is now uncommon.

MEAL, To sprinkle with meal, or to mix meal with. Little used.

Vine's Expository Dictionary of NT Words [3]

1: Ἄλευρον (Strong'S #224 — Noun Neuter — aleuron — al'-yoo-ron )

"meal" (akin to aleuo, "to grind," and therefore, lit., "what is ground"), occurs in  Matthew 13:33;  Luke 13:21 .

Wilson's Dictionary of Bible Types [4]

 2 Kings 4:41 (c) This meal may be taken to represent Christ Himself, or it may be the Word of GOD. Both CHRIST and His Word are able to dispel all poisonous thoughts in the life, and to deliver safely from the evil doctrines and teachings of false religions. Since the meal offering represents the life of CHRIST offered to the Father instead of our own, we are rather inclined to believe that this meal may represent the blessed Person of our Lord Jesus who delivers from all evil doctrines, and every poisonous faith.

Hastings' Dictionary of the Bible [5]

MEAL. See Food, § 2 .
