Numbers 34:9

And the border shall go on to Ziphron, and the goings out of it shall be at Hazar–enan: this shall be your north border.

Cross-references

In Numbers 34:7, the northern border begins at Mount Hor — this verse continues the same boundary description from west to east.

In Ezekiel 47:17, Hazar-enan appears as the northern border terminus — identical to the location here.
