Job 1:5

5 And when the days of their feasting had been completed, Job sent to them and sanctified them, and, getting up at dawn, he offered holocausts for each one. For he said, “Perhaps my sons have sinned and have not praised God in their hearts.” So Job did all the days. ^{▼▼1:5The phrase ‘benedixerint Deo’ literally means ‘they have blessed God.’ But the expression ‘bless God’ in ancient times was sometimes used to mean the opposite, as in ‘they have cursed God.’ Job is concerned that his sons may have sinned either by cursing God in their hearts (or attitudes), or by not blessing God. For to refrain from praising God is to curse God.(Conte)
