How amiable are thy tabernacles! or, "how lovely are thy dwellings!!" The plural is used, as in Psalms 43:3; Psalms 46:4 (also Korahite); and Psalms 132:7, either because the temple was made up of several compartments, or as a "plural of dignity."
O Lord of hosts (comp. Psalms 132:3, Psalms 132:8, Psalms 132:12).
