'Harshness' in the Bible

And the Egyptians made the children of Israel serve with harshness;

and they embittered their life with hard labour in clay and bricks, and in all manner of labour in the field: all their labour with which they made them serve was with harshness.

The weak have ye not strengthened, nor have ye healed the sick, and ye have not bound up what was broken, neither have ye brought again that which was driven away, neither have ye sought for that which was lost; but with harshness and with rigour have ye ruled over them.
