'Lacking' in the Bible

And I do see among the simple ones, I discern among the sons, A young man lacking understanding,

In the lips of the intelligent is wisdom found, And a rod is for the back of him who is lacking understanding.

Whoso is tilling the ground is satisfied with bread, And whoso is pursuing vanities is lacking heart,

Folly is joy to one lacking heart, And a man of intelligence directeth his going.

A man lacking heart is striking hands, A surety he becometh before his friend.

Near the field of a slothful man I passed by, And near the vineyard of a man lacking heart.

A leader lacking understanding multiplieth oppressions, Whoso is hating dishonest gain prolongeth days.
