‎מֶ֫שֶׁק‎ noun [masculine] acquisition, possession (?; meaning conjectured from context, from analogy of ‎מִמְשָׁק‎ q. v., and of ‎משׁך‎), only ‎וּבֶןמֶֿשֶׁק בֵּיתִי הוּא‎ ‎דַּמֶּשֶׂק אֱלִיעֶזֶר‎ Gen 15:2 (compare ‎בן‎ 8 (λ), above; Ges«GKC:128»§ 128. 2, R. 2. c) and the son of acquisition (= he who is to acquire, the heir of) my house is, etc.; ‎׳‎‎מ‎ possibly changed from ‎משׁך‎ (compare Job 28:18) for word-play with ‎דמשׂק‎, Kau and SoGn. Anm. 62, or by copyist's error, but very dubious. ᵐ5 Μασεκ (proper name, compare LagBN 78).
