Numbers 22:18-20

Young's Literal Translation

¹⁸ And Balaam answereth and saith unto the servants of Balak, `If Balak doth give to me the fulness of his house of silver and gold, I am not able to pass over the command of Jehovah my God, to do a little or a great thing;

¹⁹ and, now, abide, I pray you, in this [place], you also, to-night; and I know what Jehovah is adding to speak with me.'

²⁰ And God cometh in unto Balaam, by night, and saith to him, `If to call for thee the men have come, rise, go with them, and only the thing which I speak unto thee -- it thou dost do.'
