This verse is almost the same as 26.29, with the verbs, he overlaid (twice) and made, showing the completed action to the earlier commands, “you shall overlay” and “shall make.” The singular verb he overlaid should be made plural, “They overlaid” (New International Version and others) in order to show that Bezalel was not the only one doing the work. (See verse 8 above.)
