HaKadosh Baruch Hu Is Happy When Am Yisrael Prevail With Tefillah

“נצחך למען נא הושע”

An early commentary to one of the Rishonim explains this request based on the words of Chazal (Pesachim 119a) on the words in Tehillim (13:1 and others): “Lamnatzei’ach Mizmor leDovid” as follows: “Sing to the One Who is won over and happy about it. Come and see that HaKadosh Baruch Hu’s middah is not like that of a human being; a human being when defeated is sad, but HaKadosh Baruch Hu is happy when others prevail over Him.”

Here as well we ask “hosha na lema’an nitzchacha” – send us salvation in the merit of the tefillah that we pray in whose strength we are able, kaviyachol, to win over You and annul the difficult decrees, and You are happy about that.
