Sforno on Exodus 3:9/ספורנו על שמות ג׳:ט׳

1ועתה, seeing that all this is true. This is the meaning of the word ועתה wherever it appears. G’d said: in view of the fact that the Israelites’ complaints are justified, that they are entitled to complain, and I am aware of their pain, etc.,

2הנה צעקת בני ישראל באה אלי, I have accepted their prayer after they truly called on Me, [aware that I could help them. Ed.] They did not merely mouth these prayers to give themselves the illusion of having vented their frustrations (compare Psalms 27,36).

3וגם ראיתי את הלחץ, in view of the excessive pressure brought to bear on them, the ones applying the pressure deserve to be punished. We find a similar construction in Zecharyah 1,15:וקצף גדול אני קוצף על הגוים השאננים אשר אני קצפתי מעט והם עזרו לרעה, “and I am very angry with those nations that are at ease; for I was only angry a little; but they overdid the punishment.”
