OET interlinear NUM 22:20

uW Translation Notes:

Note 1 topic: grammar-connect-condition-fact

אִם־לִ⁠קְרֹ֤א לְ⁠ךָ֙ בָּ֣אוּ הָ⁠אֲנָשִׁ֔ים

if to=call to/for=yourself(m) they_went the,men

God is speaking as if this were a hypothetical possibility, but he means that it is actually true. If your language does not state something as a condition if it is certain or true, or if your readers might think that what God is saying is uncertain, then you could translate this as a confident statement. Alternate translation: [Since the men have come to call for you]

Note 2 topic: figures-of-speech / infostructure

וְ⁠אַ֗ךְ הַ⁠דָּבָ֛ר אֲשֶׁר־אֲדַבֵּ֥ר אֵלֶ֖י⁠ךָ אֹת֥⁠וֹ תַעֲשֶֽׂה

and,only (Some words not found in UHB: and,he_came ʼElohīm to/towards Bilˊām night and=he/it_said to=him/it if to=call to/for=yourself(m) they_went the,men get_up go with=them and,only DOM the,word which/who tell to,you DOM=him/it do )

If it would be more natural in your language, you may want to put the phrase it you shall do with or before the phrase the word that I speak to you. Alternate translation: [But you shall do only the word that I speak to you]
