I got yrw as the element "to establish" from the Anchor Bible Dictionary,
3:751, but the text there doesn't go into detail on the point. It is also
mentioned ad loc. (IE s.v. Yerushalem) at BDB. Looking further at BDB, a
parallel formulation might be Yeruel, "founded of El," from 2 Chron. 20:16
and (in a variant form) at 1 Chron. 7:2.
