¹ tn Or “in that day” (KJV).

² tn Heb “over it”; the referent (the prey) has been specified in the translation for clarity.

³ tn Heb “like the growling of the sea.”

⁴ tn Heb “and one will gaze toward the land, and look, darkness of distress, and light will grow dark by its [the land’s?] clouds.”

sn The motif of light turning to darkness is ironic when compared to v. 20. There the sinners turn light (= moral/ethical good) to darkness (= moral/ethical evil). Now ironically the Lord will turn light (= the sinners’ sphere of existence and life) into darkness (= the judgment and death).

⁵ tn Heb “in all my holy mountain.” In the most basic sense the Lord’s “holy mountain” is the mountain from which he rules over his kingdom (see Ezek 28:14, 16). More specifically it probably refers to Mount Zion/Jerusalem or to the entire land of Israel (see Pss 2:6; 15:1; 43:3; Isa 56:7; 57:13; Ezek 20:40; Ob 16; Zeph 3:11). If the Lord’s universal kingdom is in view in this context (see the note on “earth” at v. 4), then the phrase would probably be metonymic here, standing for God’s worldwide dominion (see the next line).

⁶ tn Heb “for the earth will be full of knowledge of the Lord, as the waters cover the sea.” The translation assumes that a universal kingdom is depicted here, but אֶרֶץ (’erets) could be translated “land” (see the note at v. 4). “Knowledge of the Lord” refers here to a recognition of the Lord’s sovereignty which results in a willingness to submit to his authority. See the note at v. 2.

⁷ tn Heb “in that day” (so KJV).

⁸ tn Heb “hard, severe”; cf. NAB, NRSV “cruel”; KJV “sore”; NLT “terrible.”

⁹ tn Heb “fleeing” (so NAB, NASB, NRSV). Some translate “slippery” or “slithering.”

¹⁰ tn The description of Leviathan should be compared with the following excerpts from Ugaritic mythological texts: (1) “Was not the dragon (Ugaritic tnn, cognate with Hebrew תַנִּין [tannin, translated “sea monster” here]) vanquished and captured? I did destroy the wriggling (Ugaritic ’qltn, cognate to Hebrew עֲקַלָּתוֹן [’aqallaton, translated “squirming” here]) serpent, the tyrant with seven heads (cf. Ps 74:14).” (See CTA 3 iii 38-39.) (2) “for all that you smote Leviathan the slippery (Ugaritic brh, cognate to Hebrew בָּרִחַ [bariakh, translated “fast-moving” here]) serpent, [and] made an end of the wriggling serpent, the tyrant with seven heads” (See CTA 5 i 1-3.)

sn In the Ugaritic mythological texts Leviathan is a sea creature that symbolizes the destructive water of the sea and in turn the forces of chaos that threaten the established order. Isaiah here applies imagery from Canaanite mythology to Yahweh’s eschatological victory over his enemies. Elsewhere in the OT, the battle with the sea motif is applied to Yahweh’s victories over the forces of chaos at creation and in history (cf. Pss 74:13-14; 77:16-20; 89:9-10; Isa 51:9-10). Yahweh’s subjugation of the chaos waters is related to His kingship (cf. Pss 29:3, 10; 93:3-4). Apocalyptic literature employs the imagery as well. The beasts of Dan 7 emerge from the sea, while Rev 13 speaks of a seven-headed beast coming from the sea.

¹¹ tn Heb “his praise.” The phrase stands parallel to “new song” in the previous line.

¹² tn Heb “and its fullness”; NASB, NIV “and all that is in it.”

¹³ tn Or “islands” (NASB, NIV); NLT “distant coastlands.”

¹⁴ tn The arm of the Lord is a symbol of divine military power. Here it is personified and told to arouse itself from sleep and prepare for action.

¹⁵ tn Heb “Are you not the one who smashed?” The feminine singular forms agree grammatically with the feminine noun “arm.” The Hebrew text has ַהמַּחְצֶבֶת (hammakhtsevet), from the verbal root חָצַב (khatsav, “hew, chop”). The Qumran scroll 1QIsa^a has, probably correctly, המחצת, from the verbal root מָחַץ (makhats, “smash”) which is used in Job 26:12 to describe God’s victory over “the Proud One.”

¹⁶ tn This title (רַהַב, rahav, “proud one”) is sometimes translated as a proper name: “Rahab” (cf. NAB, NASB, NIV, NRSV). It is used here of a symbolic sea monster, known elsewhere in the Bible and in Ugaritic myth as Leviathan. This sea creature symbolizes the forces of chaos that seek to destroy the created order. In the Bible “the Proud One” opposes God’s creative work, but is defeated (see Job 26:12; Ps 89:10). Here the title refers to Pharaoh’s Egyptian army that opposed Israel at the Red Sea (see v. 10, and note also Isa 30:7 and Ps 87:4, where the title is used of Egypt).

¹⁷ tn The words “did you not” are understood by ellipsis (note the preceding line). The rhetorical questions here and in v. 10 expect the answer, “Yes, you certainly did!”

¹⁸ tn Hebrew תַּנִּין (tannin) is another name for the symbolic sea monster. See the note at 27:1. In this context the sea creature represents Egypt. See the note on the title “Proud One” earlier in this verse.

¹⁹ tn Heb “and he remembered the days of antiquity, Moses, his people.” The syntax of the statement is unclear. The translation assumes that “his people” is the subject of the verb “remembered.” If original, “Moses” is in apposition to “the days of antiquity,” more precisely identifying the time period referred to. However, the syntactical awkwardness suggests that “Moses” may have been an early marginal note (perhaps identifying “the shepherd of his flock” two lines later) that has worked its way into the text.

²⁰ tn The Hebrew text has a plural form, which if retained and taken as a numerical plural, would probably refer to Moses, Aaron, and the Israelite tribal leaders at the time of the Exodus. Most prefer to emend the form to the singular (רָעָה, ra’ah) and understand this as a reference just to Moses.
