It's already written in scripture who he chose to be his chosen people. If you're asking was it faith and obedience, - no it wasn't. They had many times of wandering faith and lack of obedience, and yet they were the people he chose.
Could it also be possible that Yahweh raised up the Hebrew Israelites [and later the Judean/Jewish NT High Priests/Pharisees]to show His power thru them, specifically, the fulfillment of the destruction of 70ad OC Jerusalem/Temple/Priesthood?
Notice how Pharaoh is shown being raised up to show His power thru him and to the Hebrews:
Exodus 9:16
And in very deed for this
cause have
I raised thee up, for to shew in thee my power; and that my name may be declared throughout all the earth.
Exodus 10:1-2
And Yahweh said unto Moses, "Go! in unto Pharaoh: for I have hardened his heart, and the heart of his servants, that I might shew these my signs before him: …"
Paul quotes that passage here:
Romans 9:17
for the Writing saith to Pharaoh<5328> -- '
For this very thing I did raise thee up, that I might shew in thee My power, and that My name might be declared in all the land;'
The Pharisees are never mentioned in the OT, but when I decided to see the meaning of the greek word for "pharisee", I was pretty astonished.
Exodus 7:11
And Pharaoh however is calling to wise-men and
to ones making enchantments/03784 kashaph and they are doing even they sacred scribes of Egypt in occultisms of them so.
