Tobit 2:6

6 Remembering the word which the Lord spoke by Amos the prophet: Your festival days shall be turned into lamentation and mourning.

Tobit 2:6 In-Context

4 And taking it up carried it privately to his house, that after the sun was down, he might bury him cautiously.
5 And when he had hid the body, he ate bread with mourning and fear,
6 Remembering the word which the Lord spoke by Amos the prophet: Your festival days shall be turned into lamentation and mourning.
7 So when the sun was down, he went and buried him.
8 Now all his neighbours blamed him, saying: Once already commandment was given for thee to be slain because of this matter, and thou didst scarce escape the sentence of death, and dost thou again bury the dead?
