'Encircling' in the Bible

Under its brim gourds went around encircling it ten to a cubit, completely surrounding the sea; the gourds were in two rows, cast with the rest.

Now figures like oxen were under it and all around it, ten cubits, entirely encircling the sea. The oxen were in two rows, cast in one piece.

I will camp against you encircling you,And I will set siegeworks against you,And I will raise up battle towers against you.
