Exodus 5:20

And they met Moses and Aaron
The officers of the children of Israel, who had been with their complaints to Pharaoh:

who stood in the way as they came forth from Pharaoh;
they, had placed themselves in a proper situation, that they might meet them when they came out, and know what success they had, and which they were extremely desirous of hearing; by which they might judge in what temper Pharaoh was, and what they might for the future expect from him in consequence of their embassy.
