[Avodah] RSRH on the dalet l'shonot shel geulah

[Saul Mashbaum]

I have long been aware of the commentary of RSRH on the 'dalet lshonot
shel geulah'
which he explains on the basis of the brit bein habetarim to Avraham Avinu.
(Gerut, avdut, and inuy, predicted in the bbh-b, will be removed, in
reverse order,
ayem sham)


I was surpised to recently discover that the Klei Yakar explains this
topic exactly in the way RSRH does.

See
http://hebrewbooks.org/pdfpager.aspx?req=49295&st=&pgnum=23

This leads me to wonder about the sources of RSRH's commentary on the Torah.
In the halachic portions, RSRH often cites the relevant shitot of the
halachic masters on the halachic topic at hand . In the narrative
sections, he cites the classic biblical commentaries sparingly. Is
there any evidence that RSRH drew on the Klei
Yakar or any other biblical commentary (other than Rashi and the
Ramban)  extensively?
