And go forth unto the valley of the son of Hinnom, which is by the entry of the east gate, and proclaim there the words that I shall tell thee,
Valley of the son of Hinnom - or Tophet, south of Jerusalem, where human victims were offered, and children made to pass through the fire in honour of Moloch.
East gate - margin, sun gate, sunrise being in the east. Cocceius objects that the valley of Hinnom, which is said to be "by the entry of" that gate was at the south side. Perhaps 'the sun gate' may mean southern; [Jerome and others take hacharciyt (H2777) from cheres, a potter's vessel, which suits the context, not from cherec (H2775), the sun-the potter's gate]. Through it lay the road to the valley of Hinnom (Joshua 15:8). The potters there formed vessels for the use of the temple which was close by (cf. Jeremiah 19:10; Jeremiah 19:14; Jeremiah 18:2; Zechariah 11:13). The same as "the water gate toward the east" (Nehemiah 3:26; Nehemiah 12:37); so called from the brook Kedron. Calvin translates, as the English version and margin, 'It was monstrous perversity to tread the law under foot in so conspicuous a place, over which the sun daily rising reminded them of the light of God's law.'
