'Hard' in the Bible

You shall not show partiality in judgment; you shall hear the small and the great alike; you shall not be afraid of the face of man; for the judgment is God's: and the cause that is too hard for you, you shall bring to me, and I will hear it.

It shall not seem hard to you, when you let him go free from you; for to the double of the hire of a hireling has he served you six years: and Yahweh your God will bless you in all that you do.

If there arises a matter too hard for you in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within your gates; then you shall arise, and go up to the place which Yahweh your God shall choose;

The Egyptians dealt ill with us, and afflicted us, and laid on us hard bondage:

For this commandment which I command you this day, it is not too hard for you, neither is it far off.
