🔼The name Telaim in the Bible
The name Telaim occurs only once in the Bible, namely in 1 Samuel 15:4, where Saul musters Israel's army in order to punish Amalek for its attitude towards Israel at the time of the Exodus, a few centuries prior. The Amalekites are defeated and king Agag is captured. Saul's decision to let Agag live causes YHWH to regret having made Saul king (15:11).
Some scholars propose that this Telaim is the same as the Telem mentioned in Joshua 15:24, but note that Telaim is a Hebrew word while Telem is an Aramaic word, and although the two may have sounded somewhat similar (which actually may account for the double name), they are not similar in meaning.
🔼Etymology of the name Telaim
The name Telaim is identical to the plural word טלאים (tal'im) meaning lambs, and the identical plural word meaning "spotted ones":
For a meaning of the name Telaim, NOBSE Study Bible Name List reads Little Lambs and Jones' Dictionary of Old Testament Proper Names has Young Lambs.
BDB Theological Dictionary doesn't translate this name and lists it under the verb טלא (tala'), meaning to be spotted, which would give our name the meaning of Spotted Ones.
