Mammon

In KJV the word occurs 3 times in Lukas 16 and once in Matthew 6.

Per the Encyclopedia of religion and Ethics:

The word is not Greek, nor is it found in the Hebrew Bible. Rather, it is a Hellenized form of the Aramaic אמן (Strongs H539), which means "money / riches / worldly goods". Wyclif and Purvey translated the word by "riches", but Tindal followed the Vulgate in transliterating the word, and so did all later English versions, except Geneva.

In order to understand the meaning of the word, one would thus need to find the source thereof (since it is nog Greek) and then understand the context of that language in order to actually understand the meaning thereof. This is what they refer to as the "root word".

Exactly this "root word" is what scholars are divided on.

J Drusins (quoted in J. Buxtorf, Lexicon Chaldaicium, 1640, Basel) and Dalman (PRE xii. 153) derive the word from אמן which would mean "that on which man trusts" or, as Dalman prefers, "that which brings man into saftey"

Jastrow (Talmud Dictionary p794) - that which one accumulates

Levy (Neuhebräisches und chaldäisches Wörterbuch) - to distribute

Gesenius (Thesaurus linguae Hebreae et Chaldeae) - "hide", "that which one hides or treasures". Gen43:23, Job3:21, Pr 2:4, Is45:3, Jer41:8)
