Hinnom Valley (Revised Standard Version “valley of the son of Hinnom”) is the name of the valley south of Jerusalem.

The Jebusite city of Jerusalem is translated “the Jebusites (that is, Jerusalem)” by Revised Standard Version. It appears as though this parenthetical statement, together with the two in verses 9 and 10, were explanations added by a later scribe to make sure that the readers would understand what was meant. Good News Translation is able to avoid the interruption of a parenthetical statement in this verse, though parentheses are included by Good News Translation in verses 9 and 10.
