'Along' in the Bible

Amalek dwells in the land of the South: and the Hittite, and the Jebusite, and the Amorite, dwell in the hill country; and the Canaanite dwells by the sea, and along by the side of the Jordan."

"Please let us pass through your land: we will not pass through field or through vineyard, neither will we drink of the water of the wells: we will go along the king's highway; we will not turn aside to the right hand nor to the left, until we have passed your border."

then your south quarter shall be from the wilderness of Zin along by the side of Edom, and your south border shall be from the end of the Salt Sea eastward;

and your border shall turn about southward of the ascent of Akrabbim, and pass along to Zin; and the goings out of it shall be southward of Kadesh Barnea; and it shall go forth to Hazar Addar, and pass along to Azmon;
