What’s the difference between “from your lips” and “from your lips to God’s ears”? [duplicate]

I used this phrase in a conversation with my wife yesterday and was surprised to learn that she had never heard of it. This led me to wonder where it came from.

By request from the comments: here is a link to a Language Log post that, among other things, explains the origin of the phrase.

from your mouth to God's ear (or ... to the Gates of Heaven). May God hear what I/you say and act upon it. Or, as defined in The Taste of Yiddish by Lillian Merwin Feinsilver (1970): 'Fun zayn moyl, in Gots oyer. Lit, From his mouth into God's ear. May God hear what he has said (and fulfil it)!' The 'Gates of Heaven' may be an Arab version. ... The first expression my stem from Psalm 130:2: 'Lord, hear my voice: let thine ears be attentive to the voice of my supplications'. The phrase also appears in the orthodox Jewish prayer book.

The explanation above taken from

Nigel Rees, Cassell's Dictionary of Word and Phrase Origins (2002), p. 90

"From your lips to God's ear" appears in Arabic (من فمك لباب السما ياختي) about as much as in Hebrew (מפיך לאוזני אלוהים). The expression does not appear in Hebrew literature before the rebirth of modern Hebrew in the last century. In modern Hebrew it is commonly used in contexts such as ynet.co.il blogs that indicate that the writer believes the origin of the phrase is Arabic. I venture to guess that the expression migrated from the Arabic to the Jewish colloquial in Andalusia and from there to the Yiddish. A quote from Arabic literature of the period might answer the question more conclusively. In any event, the expression is loaned in English. The expression can be used to indicate true heartfelt agreement and can also be used sarcastically or wryly as in "would that it were so", or "insha'alah".
