OET interlinear PSA 115:14

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

יֹסֵ֣ף יְהוָ֣ה עֲלֵי⁠כֶ֑ם

give_~_increase YHWH to,you(pl)

The psalmist assumes that readers will know what Yahweh should add to you. The context of blessing families suggests that this refers to adding children or descendants. You could say that explicitly if that would be helpful to your readers. Alternate translation: [May Yahweh add children to your families]

Note 2 topic: figures-of-speech / yousingular

יֹסֵ֣ף יְהוָ֣ה עֲלֵי⁠כֶ֑ם

give_~_increase YHWH to,you(pl)

The word you is plural here because the psalmist is addressing the Israelites, so use the plural form in your translation if your language marks that distinction. Alternate translation: [May Yahweh add to all of you]

Note 3 topic: figures-of-speech / doublet

עֲלֵי⁠כֶ֑ם עֲ֝לֵי⁠כֶ֗ם

to,you(pl) to,you(pl)

The psalmist repeats to you for emphasis. If it would be clearer for your readers, you could express the emphasis in another way. Alternate translation: [to you, yes, to you]

Note 4 topic: figures-of-speech / metaphor

וְ⁠עַל־בְּנֵי⁠כֶֽם

and,to (Some words not found in UHB: give_~_increase YHWH to,you(pl) to,you(pl) and,to children_of,your(pl) )

The psalmist is speaking as if future generations were actually sons. He means descendants in general. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [and to your descendants]
