OET interlinear 2 KI 13:17

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

וַ⁠יֹּ֗אמֶר פְּתַ֧ח הַ⁠חַלּ֛וֹן קֵ֖דְמָ⁠ה

(Some words not found in UHB: and=he/it_said open the,window eastward,to and,he_opened_[it] and=he/it_said ʼElīshāˊ shoot and,he_shot and=he/it_said arrow_of victory to/for=YHWH and,an_arrow_of victory on,Aram and,you_will_defeat DOM ʼArām in,Aphek until made_an_end_of )

Since the king was holding the bow, the implication is that Elisha wanted the king to have a servant or attendant open the window. You could indicate this in your translation if that would be helpful to your readers. The UST models one way to do that.

וַ⁠יֹּ֗אמֶר פְּתַ֧ח הַ⁠חַלּ֛וֹן קֵ֖דְמָ⁠ה וַ⁠יִּפְתָּ֑ח וַ⁠יֹּ֤אמֶר אֱלִישָׁ֤ע יְרֵה֙ וַ⁠יּ֔וֹר וַ⁠יֹּ֗אמֶר חֵץ־תְּשׁוּעָ֤ה לַֽ⁠יהוָה֙ וְ⁠חֵ֣ץ תְּשׁוּעָ֣ה בַֽ⁠אֲרָ֔ם וְ⁠הִכִּיתָ֧ אֶת־אֲרָ֛ם בַּ⁠אֲפֵ֖ק עַד־כַּלֵּֽה

(Some words not found in UHB: and=he/it_said open the,window eastward,to and,he_opened_[it] and=he/it_said ʼElīshāˊ shoot and,he_shot and=he/it_said arrow_of victory to/for=YHWH and,an_arrow_of victory on,Aram and,you_will_defeat DOM ʼArām in,Aphek until made_an_end_of )

Having the king shoot an arrow eastward, in the direction of Aram, was a symbolic action by which Elisha represented Yahweh’s promise of victory over Aram and encouraged the king to trust that promise. Elisha placing his hands on the king’s hands symbolized how Yahweh would enable Jehoash to win that victory. If it would be helpful to your readers, you could explain the significance of this action in the text or in a footnote.
