'Explorers' in the Bible

Joshua son of Nun and Caleb son of Jephunneh, from the explorers [of] the land, tore their garments.

Then Moses sent out explorers to scout Jazer. They captured its towns and drove out the Amorites who were there.

He sinks his shaft far from human habitations, in a place forgotten by explorers; they hang on harnesses as they swing back and forth.
