Isaiah 51:9-10

Context

51:9 Wake up! Wake up!

Clothe yourself with strength, O arm of the Lord!¹

Wake up as in former times, as in antiquity!

Did you not smash² the Proud One?³

Did you not⁴ wound the sea monster?⁵

51:10 Did you not dry up the sea,

the waters of the great deep?

Did you not make⁶ a path through the depths of the sea,

so those delivered from bondage⁷ could cross over?

Psalms 89:49

Context

89:49 Where are your earlier faithful deeds,⁸ O Lord,⁹

the ones performed in accordance with your reliable oath to David?¹⁰

[51:9] ¹tn 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.

[51:9] ²tn 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.”

[51:9] ³tn 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).

[51:9] ⁴tn 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!”

[51:9] ⁵tn 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.

[51:10] ⁶tn The Hebrew text reads literally, “Are you not the one who dried up the sea, the waters of the great deep, who made…?”

[51:10] ⁷tn Heb “the redeemed” (so ASV, NASB, NIV, NRSV); KJV “the ransomed.”

[89:49] ⁸sn The Lord’s faithful deeds are also mentioned in Pss 17:7 and 25:6.

[89:49] ⁹tc Many medieval Hebrew mss read here יְהוָה (yehvah, “the Lord”).

[89:49] ¹⁰tn Heb “[which] you swore on oath to David by your faithfulness.”
