דִּרְשׁ֣וּ יְהוָ֣ה וְעֻזּ֑וֹ בַּקְּשׁ֖וּ פָנָ֣יו תָּמִֽיד׃
Ищите Господа и силу Его; Ищите Его лицо постоянно.
Rabbeinu Bahya
Adam was to remember where exactly he originated from and to where he would return to if he became sinful and would be expelled from Gan Eden. This is the meaning of 3,29 “to work the earth that he had been taken from.” Here the Torah already previewed man’s descendants and their habitat when it wrote quoting Cain in Genesis 4,14 הן גרשת אותי היום מעל פני האדמה, “here You have expelled me this day from the face of the earth.” Cain added ומפניך אסתר, “and I have to hide from Your benevolent presence.” He was referring to G-d’s presence, the שכינה. We find similar expressions for that meaning of “G-d’s presence [as opposed to “hiding” from G-d, something already Adam had found to be impossible. Ed.] in Psalms 24,6 מבקשי פניך, “the ones who seek out Your benevolent presence.” Another similar construction is found in Psalms 27,8 את פניך אבקש, “I will seek out Your benevolent presence.” This is also what is meant in Genesis 4,16 ויצא קין מלפני ה', ”Cain left the benevolent presence of G-d.” We find another verse telling us something similar when the prophet Jonah with whom G-d had communicated tried to escape this closeness to G-d. The Book of Jonah 1,3 describes his behaviour in these words ויקם יונה לברוח תרשישה מלפני ה', ”Jonah arose to flee to Tarshish from the benevolent presence of G-d.” It was Jonah’s intent to escape the very part of the land of Israel where G-d’s benevolent presence is manifest. Once he would accomplish this he was confident that G-d would not communicate with him further and he could abort the mission G-d wanted him to undertake.
Ibn Ezra
ורוחו And His spirit, that is His angel.25God had sent me to proclaim the future events; and He sent His angel to verify the words of the prophet. It is however possible, that I. E. connects ורוחו with שם אני ; There was I and His angel. The Gaon says, that ברוחו═ורוחו by His spirit; comp. דרשו יי ועזו seek the Lord in His strength ; but there is no necessity to assume that.
