קֹדֶשׁ qodesh "holiness". In Amos, only of Adonai's holiness 2:7; 4:2.
מִקְדָּשׁ miqdash "sanctuary". In Am 7:13 miqdash-melek "sanctuary of the king" is in parallel to beth mamlakah "house of the kingdom" clearly the "sanctuary" is a building (elsewhere, usually, it evidently refers to both temples and their precincts). So in Am 7:9 it completes and rounds out bamah "high place" to indicate that both outdoor altars and temple buildings are in view.
