'אשר ידעו ה, whom G’d had endowed with so much knowledge by turning His face to him. We have been told in Samuel I 10,6 that receiving even a small measure of prophetic insight makes the recipient an איש אחר, a different person. This is why the prophet Amos 2,11 when referring to the deeds of loving kindness performed by G’d for the people lists the fact that G’d gave many Israelites prophetic insights. The people, during Amos’ time, instead of availing themselves of the spiritual inspiration thus accessible, forbade these prophets to impart their visions, etc., reversing and frustrating G’d’s purpose. Seeing that all of G’d’s activity stems exclusively from His own personal knowledge (cannot be evaluated properly by His creatures, seeing that they are “only” His creature) the Torah records G’d as saying that אשר ידעו ה' פנים אל פנים, that in His communications with Moses and granting him insights into His ways, He did so exclusively for Moses’ benefit. This expression ידע appears repeatedly in Scriptures in this sense of endowing someone with insights. One example is Psalms 144,3 מה אדם ותדעהו, “what did man do that You should take the trouble to grant him such insights?” Another such example is found in Exodus 33,17 ואדעך בשם, “I granted you some insights about My essence, by making you familiar with some of My attributes.” [my translation. Ed.] Compare also Exodus 2,25 Psalms1,6 and numerous other examples. [If I do not err, the author feels that seeing that G’d’s omniscience is axiomatic in Judaism, such phrases as the ones quoted cannot simply mean “G’d knew,” for there would be no point in the Torah stating the obvious. They must therefore imply that G’d communicated some of His knowledge. In Exodus 2,25 the Torah meant to tell us that the Jewish people would shortly become aware that G’d knew all about their condition and would do something about it, something that would also raise their spiritual level as a result.

and you perish in the way Like the matter that is stated (above 1:16): “but the way of the wicked shall perish.”
Radak
and ye perish in the way, For His wrath will soon be kindled: – Soon, because ye continue in your wickedness, His anger will burn upon you, as if to say, If ye do not quickly repent. And the interpretation of and ye perish in the way is as (in the verse) “and the way of the wicked shall perish” (Ps. 1:6). And behold the way perishes and they are perishing because of their way which is perishing, as “an oak fading as to its leaves” (Is. 1:30). Because the leaves are fading the oak is called a fading one. And so, “the torn of clothes” (2 Sam. 13:31(2)), and elsewhere, for the clothes are torn and not they (i.e. the wearers), and they are called torn because of their clothes which are torn. And so (Jer. 41:5), “Shaven as to their beards and rent of clothes” and other similar instances. And he says:
