'Supposing' in the Bible

The Jews who were with her in the house consoling her saw that Mary got up quickly and went out. So they followed her, supposing that she was going to the tomb to cry there.

“Woman,” Jesus said to her, “why are you crying? Who is it you are looking for?”Supposing He was the gardener, she replied, “Sir, if you’ve removed Him, tell me where you’ve put Him, and I will take Him away.”
