a row: a line of matching things set side by side in a fixed, repeating order
This word names any orderly line of like items arranged one beside the next. It is a plain, concrete term, and English "row" fits it closely in every place it appears. What ties its uses together is the idea of deliberate, repeated arrangement: not a random cluster but a set line, counted and even.
In practice it shows up in two settings. It names the four rows of engraved gems set into the high priest's breastpiece, and it names rows in building and decoration: courses of cut stone, ranks of pillars, tiers of window frames, and bands of carved pomegranates, gourds, or oxen running around the temple furnishings. In both cases the point is the same, that the maker laid things out in orderly lines.
Because the word is so ordinary, English versions freely swap among "row," "rank," and "course" depending on what is being lined up, but the Hebrew behind them is one and the same word.
