'Trust' in the Bible

And the bramble said unto the trees, If in truth ye anoint me king over you, then come and put your trust in my shadow: and if not, let fire come out of the bramble, and devour the cedars of Lebanon.

And Gaal son of Ebed cometh -- also his brethren -- and they pass over into Shechem, and the masters of Shechem trust in him,

but Sihon would not trust Israel to pass through his territory. Instead, Sihon gathered all his people, camped at Jahaz, and fought with Israel.
