Bildad describes the fate of the wicked (verses 5–21)[11]
Whereas in their first speech both Eliphaz and Bildad focus on the nature of God, in their second speech both explore the topic of the fate of the wicked, suggesting in the course of the conversation they become more convinced that Job is among the wicked.[11]
Bildad rebukes Job (18:1–5)
The chapter opens with Bildad's rebuke of Job for considering his friends as fools (like cattle, verse 3; cf Job 17:10) and urge for Job to be sensible and have broader perspective.[11]
Verse 5
[Bildad said:] "“Indeed, the light of the wicked is put out,
“Indeed”: translated from the Hebrew word גַּם, gam, which can be rendered as "also; moreover", that is, "in view of what has just been said."[13]
Job expresses his despair (18:5–21)
The second part of the chapter contains Bildad's extended description of the fate of the wicked: insecurity, terror and hopelessness.[11] It can be implied that Job is at least on the way to be one of the wicked, so the whole section serves as a strong warning to Job.[11] This is strongly emphasized in the last two verses of the chapter (verses 20–21), which demonstrates Bildad's view of Job's descent into the wickedness.[14]
Verse 20
[Bildad said:] "They who come after him will be astonished at his day,
as they who went before were seized with fright."[15]
"Those who come after him": translated from the Hebrew word אַחֲרֹנִים, ʾakharonim, which can be rendered "those in the west" as in NKJV, ESV, etc.[16][17]
"They who went before": translated from the Hebrew word קַדְמֹנִים, qadmonim, which can be rendered "those in the east" as in NKJV, ESV, etc.[18][17]
In relation to the geography, there are Hebrew terms of the seas: "the hinder sea", referring to the Mediterranean (in the "West"), and "the front sea", referring to the Dead Sea (Zechariah 14:8), namely, the "East".[17] The Greek Septuagint (among other versions) understood the verse as temporal: "the last groaned for him, and wonder seized the first".[17]
