Isaiah 57:5

57:5 you who practice ritual sex ¹  under the oaks and every green tree,

who slaughter children near the streams under the rocky overhangs. ² 

Ezekiel 6:13

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, ³  the places where they have offered fragrant incense to all their idols.

Hosea 4:13

4:13 They sacrifice on the mountaintops,

and burn offerings on the hills;

they sacrifice ⁴  under oak, poplar, and terebinth,

because their shade is so pleasant.

As a result, your daughters have become cult prostitutes,

and your daughters-in-law commit adultery!

[57:5]  ¹ tn Heb “inflame yourselves”; NRSV “burn with lust.” This verse alludes to the practice of ritual sex that accompanied pagan fertility rites.

[57:5]  ² sn This apparently alludes to the practice of child sacrifice (cf. TEV, CEV, NLT).

[6:13]  ³ 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).

[4:13]  ⁴ tn The phrase “they sacrifice” is not repeated in the Hebrew text here but is implied by parallelism; it is provided in the translation for the sake of clarity.
