Genesis 27:20

And Isaac said to his son, How is it that thou have found it so quickly, my son? And he said, Because LORD thy God sent me good speed.

And he said, O LORD, the God of my master Abraham, send me, I pray thee, good speed this day, and show kindness to my master Abraham.

Thou shall not take the name of LORD thy God in vain, for LORD will not hold him guiltless who takes his name in vain.

Will ye speak unrighteously for God, and talk deceitfully for him?
