Re G(1) in Ahiqar (TAD C1.1 .3): In Assyrian administrative terminology ṣābītu refers more to authority than simply possession. See most recently A.Y. Ahmad and J.N. Postgate, Archives from the Domestic Wing of the the North-West Palace at Kalhu/Nimrud (Nabu Publications, 2007) p. 8n. All usages are apparently from Akkadian; see extensive discussion in AIOA 95. For this reason the two homonymous verbs have been separated.
