Ezekiel 6:13

Then you will know that I am the Lord – when their dead lie among their idols around their altars, on every high hill and all the mountaintops, under every green tree and every leafy oak, ¹  the places where they have offered fragrant incense to all their idols.

1Ki 14:23; 2Ki 16:4; Isa 1:29; Isa 37:20,36-38; Isa 57:5-7; Isa 65:3,4; Isa 66:17; Jer 2:20; Jer 3:6; Eze 6:4-7; Eze 20:28; Ho 4:13

¹ sn By referring to every high hill…all the mountaintops…under every green tree and every leafy oak Ezekiel may be expanding on the phraseology of Deut 12:2 (see 1 Kgs 14:23; 2 Kgs 16:4; 17:10; Jer 2:20; 3:6, 13; 2 Chr 28:4).
