🔼The name Elim in the Bible
The name Elim belongs to a dreamlike oasis in the wilderness, with twelve springs of water and seventy palms (תמרים, see the name Tamar). The Israelites camped there right after the bitter waters of Marah incident, immediately following the crossing of the Sea of Reeds (Exodus 15:27, 16:1, Numbers 33:9-10).
🔼Etymology of the name Elim
The name Elim is generally assumed to derive from the plural of the noun איל ('ayil), which would be spelled as אילים; it may be that this name stems from a time before the Hebrews added the primary vowels (such as the י, yod, prior to the masculine plural ם). The noun איל ('ayil) denotes something that sticks out or protrudes:
For a meaning of the name Elim, Jones' Dictionary of Old Testament Proper Names proposes A Grove Of Oaks and adds "or palms". Elim was obviously in the desert and oaks don't grow in that kind of climate.
Likewise BDB Theological Dictionary declares: "אילם = place of terebinths or other great trees," and equates it with the name עילם, Elam of Genesis 14:1, which is really a completely different name.
