Or HaChaim on Exodus 6:5/אור החיים על שמות ו׳:ה׳

1 וגם אני שמעתי את נאקת בני ישראל, "I have also heard the groaning of the children of Israel, etc." The word וגם, "and also," refers to something over and beyond the prayers of the Israelites to the attribute of Mercy. In addition to the prayers of the Israelites and G'd's love for the patriarchs, there was a third consideration which had a bearing on G'd's timetable for the redemption, namely the outcry of the Israelites due to the torture they were experiencing. This third element is referred to by G'd in our verse by the words: וגם אני, "also I." G'd reveals His name of אני as an aspect of the attribute of Mercy. Previously, this name had only appeared in conjunction with the tetragram. G'd revealed that there are occasions when people's groanings even when not accompanied by verbalised prayer reach the attribute of Mercy and evoke a response. This is why He added אשר מצרים מעבידים אותם, "the manner in which the Egyptians have enslaved them." I refer the reader to my comments on Exodus 2,23 in this respect.

2ואזכר את בריתי, "I have remembered My covenant." G'd means that He remembered both parts of the covenant, i.e. to redeem the people and to bring them to the Holy Land. [This had been a covenant with the patriarchs. What is new is that the present generation of Israelites would be the ones who would experience realisation of that covenant.] In this instance G'd spoke about a covenant which had not yet been spelled out but which follows immediately in the next four verses. G'd repeats the covenant only as an explanation of why He has advanced the date it is to become effective. The commentators who understand this covenant as a promise to punish the Egyptians are wrong; none of this has been mentioned in the verse following this declaration.
