Moses
Exodus 5:8ESV·traditional attribution

But the number of bricks that they made in the past you shall impose on them, you shall by no means reduce it, for they are idle. Therefore they cry, ‘Let us go and offer sacrifice to our God.’

Matthew Henry Presbyterian @wholebiblehenry

Finding that Pharaoh had no veneration at all for God, Moses and Aaron next try whether he had any compassion for Israel, and become humble suitors to him for leave to go and sacrifice, but in vain. I. Their request is very humble and modest, Exo 5:3. They make no complaint of the rigour they were ruled with.

Commenting on Exodus 5:3-9

John Gill Reformed Baptist @doctorgill

And the tale of the bricks, which they did make heretofore, you shall lay upon them,.... Oblige them to make and bring in the same number of bricks they used to do, when straw was brought to them and given them; by which it appears, that their daily task was such a number of bricks: you shall not diminish ought thereof; not make any abatement...
