Rashi on Leviticus 19:12/רש"י על ויקרא י״ט:י״ב

1ולא תשבעו בשמי AND YE SHALL NOT SWEAR BY MY NAME [TO A LIE] - Why is this stated at all (how does the particular form of words used here tell us more than is contained in the Third Commandment)? Since it is said (Exodus 20:7) “Thou shalt not take the name of the Lord (‎'ה) thy God in vain”, I might have inferred that one is not liable except he swore by the "Proper Name” of the Lord (שם המיוחד). Whence do I know that all names that are descriptive of God's attributes (Adonay, Rachum, Chanun etc.) are included in this prohibition? Because Scripture states “ye shall not swear by My Name to a lie", thus implying by any Name I have (Sifra, Kedoshim, Section 2 6).
