'Appropriate' in the Bible

Moses said, "It isn't appropriate to do so; for we shall sacrifice the abomination of the Egyptians to Yahweh our God. Behold, shall we sacrifice the abomination of the Egyptians before their eyes, and won't they stone us?

Now because we eat the salt of the palace, and it is not appropriate for us to see the king's dishonor, therefore have we sent and informed the king;

There is one who scatters, and increases yet more. There is one who withholds more than is appropriate, but gains poverty.

Delicate living is not appropriate for a fool, much less for a servant to have rule over princes.
