Numbers 22:15-19

And Balak sent yet again princes— Balak, apprehensive that his first deputation to Balaam was not honourable enough, and that his presents and promises were not sufficiently large, made a second deputation, and sent persons more eminent, with the highest promises, Numbers 22:17. This proposal was at first displeasing to the prophet; at least he returned a noble answer, Numbers 22:18. But it appears from the next verse, that this motion proceeded less from a sincere and solid piety, than a servile fear, and a virtue merely transient and superficial, Numbers 22:19.
