Sirach 18:17LXX

15My son, in thy good deeds, make no complaint, and when thou givest any thing, add not grief by an evil word.

16Shall not the dew assuage the heat? so also the good word is better than the gift.

17Lo, is not a word better than a gift? but both are with a justified man.

18A fool will upbraid bitterly: and a gift of one ill taught consumeth the eyes.

19Before judgment prepare thee justice, and learn before thou speak.
