Exodus Chapter 5, Verse 9
From BibleWiki
9: Let there more work be laid upon the men, that they may labour
therein; and let them not regard vain words.
9: Let the works of these men be made grievous, and let them care for these things, and not care for vain words.
"Let the work be heavy (press heavily) upon the people, and they shall make with it (i.e., stick to their work), and not look at lying words." By "lying words" the king meant the words of Moses, that the God of Israel had appeared to him, and demanded a sacrificial festival from His people.
