'Undesirable' in the Bible

Saul and the people spared Agag and the best of the sheep, the oxen, the fatlings, the lambs, and everything that was good, and they were not willing to destroy them entirely; but everything that was undesirable or worthless they destroyed completely.

“Does the ear not put words to the test,Just as the palate tastes its food [distinguishing between the desirable and the undesirable]?

“Is this man Coniah a despised, shattered jar?Or is he an undesirable vessel?Why have he and his descendants been hurled outAnd cast into a land that they had not known?

On all the housetops of Moab and in its streets there is lamentation everywhere; for I have broken Moab like an undesirable vessel,” declares the Lord.

Gather yourselves together;gather together, undesirable nation,

while Paul deemed it undesirable to have as their companion one who had deserted them in Pamphylia and had not gone on with them to the work.
