1 Samuel 16:2

Samuel said, “How can I go? If Saul hears it, he will kill me.” Yahweh said, “Take a heifer with you, and say, ‘I have come to sacrifice to Yahweh.’

And Samuel said, How can I go? if Saul hear it, he will kill me. And the LORD said, Take an heifer with thee, and say, I am come to sacrifice to the LORD.
