Exodus 5:22

He expostulated with him. He knew not how to reconcile the providence with the promise, and the commission he had received. Is this God's coming down to deliver Israel? Must I who hoped to be a blessing to them become a scourge to them? By this attempt to get them out of the pit, they are but sunk the farther into it. Wherefore hast thou so evil entreated this people — Even when God is coming towards his people in ways of mercy, yet sometimes he takes such methods that they may think themselves but ill — treated: when they think so, they should go to God by prayer, and that is the way to have better treatment in God's good time. Why is it that thou hast sent me — Pharaoh has done evil to this people, and not one step seems to be taken towards their deliverance. It cannot but sit very heavy upon the spirits of those whom God employs for him, to see that their labour doth no good, and much more to see that it doth hurt, eventually, though not designedly.
