אַחֲרֵ֨י יְהוָ֧ה אֱלֹהֵיכֶ֛ם תֵּלֵ֖כוּ וְאֹת֣וֹ תִירָ֑אוּ וְאֶת־מִצְוֺתָ֤יו תִּשְׁמֹ֙רוּ֙ וּבְקֹל֣וֹ תִשְׁמָ֔עוּ וְאֹת֥וֹ תַעֲבֹ֖דוּ וּב֥וֹ תִדְבָּקֽוּן׃
너희는 너희 하나님 여호와를 순종하며 그를 경외하며 그 명령을 지키며 그 목소리를 청종하며 그를 섬기며 그에게 부종하고
Ramban
AFTER THE ETERNAL YOUR G-D SHALL YE WALK. This is a commandment that we follow His counsel, and of Him alone shall we inquire concerning every hidden thing and inquire concerning the future, as it is written, and she went to inquire of the Eternal;145Genesis 25:22. because the people come unto me to inquire of G-d.146Exodus 18:15. And so did the Israelites do with the prophets, [as it is said,] Is there not here a prophet of the Eternal, that we may inquire of the Eternal through him?;147II Kings 3:11. that the Eternal thy G-d may tell us the way wherein we should walk, and the thing we should do.148Jeremiah 42:3. And in the Sifre it is stated:149Sifre, R’eih 85. “After the Eternal your G-d [shall ye walk] — this refers to the cloud [of Glory].”150See Ramban to Numbers 9:19: “They did the will of G-d in following after the cloud [of Glory].” See also my Hebrew commentary here p. 406. This is as we have explained, that we are to hearken to the “voice” of His signs and follow His counsel.
Ibn Ezra
after God your God must you walk you must imitate His acts, to the best of your ability, and pursue His ways.
