OET interlinear HERO (JDG) 14:12

uW Translation Notes:

Note 1 topic: figures-of-speech / events

אִם־הַגֵּ֣ד תַּגִּידוּ֩ אוֹתָ֨⁠הּ לִ֜⁠י שִׁבְעַ֨ת יְמֵ֤י הַ⁠מִּשְׁתֶּה֙ וּ⁠מְצָאתֶ֔ם

if (Some words not found in UHB: and=he/it_said to/for=them Shimshvōn/(Samson) tell now to/for=you(pl) riddle if to_tell explain ,it to=me seven_of days_of of,the_feast and,you(pl)_will_find_[it]_out and,I_will_give to/for=you(pl) thirty linen_garments and=thirty changes_of clothes )

Samson is describing one event before describing another event that would have to precede it. In your translation, you may wish to relate these events in the order in which they happened. Alternate translation: [If you are able to figure it out and tell me the answer during the seven days of the feast]

Note 2 topic: figures-of-speech / reduplication

אִם־הַגֵּ֣ד תַּגִּידוּ֩ אוֹתָ֨⁠הּ

if (Some words not found in UHB: and=he/it_said to/for=them Shimshvōn/(Samson) tell now to/for=you(pl) riddle if to_tell explain ,it to=me seven_of days_of of,the_feast and,you(pl)_will_find_[it]_out and,I_will_give to/for=you(pl) thirty linen_garments and=thirty changes_of clothes )

Samson is repeating forms of the verb declare in order to intensify the idea that it expresses. If your language can repeat words for intensification, it would be appropriate to do that here in your translation. If not, your language may have another way of expressing the emphasis. Alternate translation: [If in fact you are able to declare it]
