TSK · Genesis 42:15

Joseph saw his brothers, and he recognized them, but acted like a stranger to them, and spoke roughly with them. He said to them, "Where did you come from?" They said, "From the land of Canaan to buy food."

Send one of you, and let him get your brother, and you shall be bound, that your words may be tested, whether there is truth in you, or else by the life of Pharaoh surely you are spies."

"The man, the lord of the land, spoke roughly with us, and took us for spies of the country.

Judah spoke to him, saying, "The man solemnly warned us, saying, 'You shall not see my face, unless your brother is with you.'

We said to my lord, 'We have a father, an old man, and a child of his old age, a little one; and his brother is dead, and he alone is left of his mother; and his father loves him.'

You said to your servants, 'Unless your youngest brother comes down with you, you will see my face no more.'

You shall fear Yahweh your God; and you shall serve him, and shall swear by his name.

When Saul saw David go forth against the Philistine, he said to Abner, the captain of the army, "Abner, whose son is this youth?" Abner said, "As your soul lives, O king, I can't tell."

Though they say, 'As Yahweh lives;' surely they swear falsely."

"Again you have heard that it was said to them of old time, 'You shall not make false vows, but shall perform to the Lord your vows,'

But above all things, my brothers, don't swear, neither by heaven, nor by the earth, nor by any other oath; but let your "yes" be "yes," and your "no," "no;" so that you don't fall into hypocrisy.
