Concise Bible Dictionary:
1. attiq. The signification of this word is not now definitely known: some suppose it to signify a colonnade (Ezek. 41:15-16; Ezek. 42:3, 5).
2. rahat, “to be collected or drawn together.” It is translated “gutters” in Genesis 30:38,41, and “troughs” in Exodus 2:16, in which water was collected for the cattle. Song of Solomon 7:5 is better translated “The king is held by the tresses” of the “hair” mentioned in the line before.
