OET interlinear HERO (JDG) 5:4

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

יְהוָ֗ה בְּ⁠צֵאתְ⁠ךָ֤ מִ⁠שֵּׂעִיר֙ בְּ⁠צַעְדְּ⁠ךָ֙ מִ⁠שְּׂדֵ֣ה אֱד֔וֹם

YHWH (Some words not found in UHB: YHWH when,you,went_out from,Seir when,marched,you from,the_region_of ʼEdōm earth/land trembled also/yet heavens poured also/yet clouds poured water )

The song is speaking as if Yahweh had literally traveled from or across the land of Seir, that is, Edom, in order to lead the Israelites into battle against Sisera. This could mean: (1) that the song is envisioning Mount Sinai as Yahweh’s dwelling place on earth and describing the route that Yahweh would have taken from there to the battlefield. Alternate translation: [Yahweh, when you came across Seir to fight against Sisera, when you marched across the fields of Edom]; (2) that the song is referring to the time when the Israelites left Edom to start conquering the people in Canaan and speaking of Yahweh as if he had been a warrior leading the Israelite army at that time. Alternate translation: [Yahweh, it was just like the time when you first led our armies into Canaan from Seir. It was as if you marched ahead of us across the fields of Edom]

Note 2 topic: figures-of-speech / genericnoun

מִ⁠שְּׂדֵ֣ה אֱד֔וֹם

(Some words not found in UHB: YHWH when,you,went_out from,Seir when,marched,you from,the_region_of ʼEdōm earth/land trembled also/yet heavens poured also/yet clouds poured water )

The song is not referring to a specific field in Edom. It means the cultivated land in Edom in general. It may be more natural in your language to express this meaning by using a plural form. Alternate translation: [from the fields of Edom]

Note 3 topic: figures-of-speech / explicit

אֶ֣רֶץ רָעָ֔שָׁה גַּם־שָׁמַ֖יִם נָטָ֑פוּ גַּם־עָבִ֖ים נָ֥טְפוּ מָֽיִם

earth/land (Some words not found in UHB: YHWH when,you,went_out from,Seir when,marched,you from,the_region_of ʼEdōm earth/land trembled also/yet heavens poured also/yet clouds poured water )

The song seems to be referring implicitly to the great storm that rendered Sisera’s chariots useless for the battle. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [the earth trembled from the thunder and there was a heavy downpour]
