OET interlinear 1 KI 7:21

uW Translation Notes:

Note 1 topic: figures-of-speech / synecdoche

וַ⁠יָּ֨קֶם֙ אֶת־הָֽ⁠עַמֻּדִ֔ים

(Some words not found in UHB: and,he_set_up DOM the,pillars to,the_porch_of of,the_temple and,he_set_up DOM the,pillar (the),right and=he/it_called DOM his/its=name Yākīn/(Jachin) and,he_set_up DOM the,pillar (the),left and=he/it_called DOM his/its=name Boˊaz )

The author is using Hiram, whom he represents with the pronoun he, one person who was involved in this action, to represent everyone who was involved. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [And Hiram and his workers set up the pillars]

Note 2 topic: figures-of-speech / explicit

אֶת־הָ⁠עַמּ֣וּד הַ⁠יְמָנִ֗י & אֶת־הָ⁠עַמּ֣וּד הַ⁠שְּׂמָאלִ֔י

DOM DOM the,pillar (the),right & DOM DOM the,pillar DOM (Some words not found in UHB: and,he_set_up DOM the,pillars to,the_porch_of of,the_temple and,he_set_up DOM the,pillar (the),right and=he/it_called DOM his/its=name Yākīn/(Jachin) and,he_set_up DOM the,pillar (the),left and=he/it_called DOM his/its=name Boˊaz )

See how you translated the similar expression in 6:8. Alternate translation: [the south pillar … the north pillar]

Note 3 topic: figures-of-speech / explicitinfo

וַ⁠יִּקְרָ֤א אֶת־שְׁמ⁠וֹ֙ יָכִ֔ין

(Some words not found in UHB: and,he_set_up DOM the,pillars to,the_porch_of of,the_temple and,he_set_up DOM the,pillar (the),right and=he/it_called DOM his/its=name Yākīn/(Jachin) and,he_set_up DOM the,pillar (the),left and=he/it_called DOM his/its=name Boˊaz )

It might seem that the expression called its name contains extra information that would not be natural to express in your language. If so, you could shorten it. Alternate translation: [and called it Jachin] or [and named it Jachin]
