The pronoun it could refer to: (1) their tongue or (2) the arrow (see 64:7). If it would be helpful in your language, you could clarify this for your readers. Alternate translation: [And their tongue will make them stumble] or [And the arrow will make them stumble]

לְשׁוֹנָ֑⁠ם

(Some words not found in UHB: and,he,shot_at_them ʼElohīm arrow suddenly they_were wounds_of,their )

Here, their tongue represents their harmful words. If it would be helpful in your language, you could use an equivalent expression or state the meaning plainly. Alternate translation: [their own words] or [what they themselves have said]

Note 3 topic: figures-of-speech / hyperbole

יִ֝תְנֹדֲד֗וּ כָּל־רֹ֥אֵה בָֽ⁠ם

(Some words not found in UHB: and,he,shot_at_them ʼElohīm arrow suddenly they_were wounds_of,their )

The psalmist is saying Everyone seeing them will flee as a generalization for emphasis. If it would be clearer in your language, you could express the emphasis in a different way. Alternate translation: [All who see them will flee] or [People who see them will flee]
