Midrash for Exodus 35:27

Because the leaders were slow to bring their gifts, a letter is omitted from their names. Thus in Scripture the word for leader lacks one yod.¹⁸The yod, which comprises half of the name of God, was removed to indicate their slothfulness. Later, however, they helped in the work of the Tabernacle, joining Bezalel and Oholiab in their labors and the wise men in their work, as is said: And every wise-hearted man that wrought (Exod. 36:8). And the women spun the purple curtains, as is said: And all the women whose hearts stirred them up in wisdom spun the goats’ hair (ibid. 35:26).
