You are in luck! Not everyone has an explanation about what’s written in the original Hebrew on this topic, but I do!

Scriptural Mormonism: Refuting Jeff Durbin on "Mormonism"
In Job 1:6, we read the following:
Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them.
In this text, Satan is presented as being among the “Sons of God” (בני האלהים) This can be seen in the verb יצב (to take [their] stand/position”) and that Satan is said to be in their “midst,” that is,
he belongs among their ranks, clearly demonstrating that the theology of Job holds to a “Satan” who has real, ontological existence, in contradistinction to some Christadelphian interpretation of the “Satan” texts in Job. When one examines the phrase, “among them” (KJV), one finds that the Hebrew is a phrase consisting of the prefixed preposition (בְּ) meaning “in/among” and (תָּוֶךְ). When one examines the other instances of this phrase in the Hebrew Bible,
it denotes someone being a member of a group, not independent thereof (e.g., Exo 28:33; Lev 17:8, 10, 13; Num 1:47; 5:3; 15:26, 29, etc.); indeed, commentators such as David J.A. Clines states that the phrase regularly denotes membership of the group in question (See Clines,
Job 1-20 [Word Biblical Commentary, 1989], 19). The bare term תָּוֶךְ also denotes membership, not independence, of the group in question (cf. Gen 23:10; 40:20; 2 Kgs 4:13).
Furthermore, the “Satan” in Job 1:6, in Hebrew, is not just the bare term (שָׂטָן), meaning an “adversary,” which, in and of itself, can denote anyone who opposes another, whether divine or not (e.g., the angel of the Lord is referred to as an adversary or שָׂטָן in Num 22:22), but is coupled with the definite article (השטן), “
the satan,” which denotes the supernatural tempter (cf. Zech 3:2); one should compare this with similar Greek locutions in the LXX and NT such as such as ο σατανας (Sirach 21:27; Matt 12:26; Mark 3:26; 4:15; Luke 10:18; 11:18; 13:16; 22:31; John 13:27; Acts 5:3; 26:18; Rom 16:20; 1 cor 5:5; 7:5; 2 Cor 2:11; 11:14; 1 Thess 2:18; 2 Thess 2:9; 1 Tim 1:20; 5:15; Rev 2:9, 13, 24; 3:9; 12:9; 20:2, 7); ο διαβολος (Matt 4:1,5,8,11; 13:39; 25:41; Luke 4:2,3,6,13; 8:12; John 8:44; 13:2; Acts 10:38; Eph 4:27; 6:11; 1 Tim 3:6, 7; 2 Tim 2:26; Heb 2:14; James 4:7; 1 John 3:8, 10; Jude 1:9; Rev 2:10; 12:12; 20:10) and ο πειραζω (Matt 4:3; 1 Thess 3:5), all denoting the external, supernatural tempter in most of Christian theologies (some small groups denying a supernatural Satan notwithstanding).
