2,629. Swearing Through a Descriptor or a Curse

Hilchos Shevuos 2:2

There’s no difference between taking an oath/having one imposed using the Tetragrammaton (i.e., God’s “four-letter” Name) or using one of the terms we use to describe Him, such as “the Gracious One,” “the Merciful One” or “the Long-Suffering One,” etc. This is a complete oath in any language. The same is true of a statement of curse, so long as one uses one of God’s names or one of the terms that we use to describe Him. For example, if one says, “May the one who eats such-and-such be cursed to God" or “cursed to the Merciful One,” etc. and he then eats that thing, he has made a false oath. The same rules apply to the other types of oaths.

Hilchos Shevuos 2:3

Similarly, if a person says that he’s making “an oath to God” or “to the Gracious One” not to eat but he eats, that a certain person is a woman but it’s a man, that he doesn’t owe a debt but he does, or that he has no relevant testimony but he does – in all of these cases, he’s liable.
