'Hard' in the Bible

They had worn-out, patched sandals on their feet and dressed in worn-out clothes. All their bread was dry and hard.

This bread of ours was warm when we packed it in our homes the day we started out to meet you, but now it is dry and hard.

The Ephraimites did not conquer the Canaanites living in Gezer. The Canaanites live among the Ephraimites to this very day and do hard labor as their servants.

Whenever the Israelites were strong militarily, they forced the Canaanites to do hard labor, but they never totally conquered them.

I gave you a land in which you had not worked hard; you took up residence in cities you did not build and you are eating the produce of vineyards and olive groves you did not plant.'
