catch, gather, (take) for a prey, rob(-ber), spoil, take (away, spoil), X utterly

Boyd’s Bible Dictionary:

Plunder seized by violence, as the spoils of an army or of bandits
(1 Sam. 30:19-22); but in Ex. 3:22, the sense is that of recovery without violence of unjustly taken property. David instituted very strict regulations for the division of spoils of war among his soldiers (1 Sam. 30:20-25).

“Robbery” From Concise Bible Dictionary:

(breaking, riving). Oppression, pillage, and thievery formed almost an employment among nomad tribes (Gen. 16:12; Judg. 2:14; Luke 10:30; John 18:40).

“Spoil” From Concise Bible Dictionary:

The booty that was seized upon by an army when a city was taken. Except when forbidden by God, as in the case of Jericho, it was considered a lawful prize; and it was thus the Israelites suffered when their cities were captured by their enemies (Deut. 20:14; 2 Kings 21:14; Isa. 42:22).

“Spoil, To” From Concise Bible Dictionary:

The kingdom of Satan was spoiled by One stronger than he when the Lord Jesus cast out demons from those possessed, and also especially when Satan’s power was annulled on the cross (Matt. 12:29; Mark 3:27; Col. 2:15; Heb. 2:14). The Hebrew believers had taken joyfully the plunder of their goods (Heb. 10:34). The Colossians were warned lest any should spoil (make a prey of) them through philosophy (Col. 2:8), a caution surely needed in the present day.
