Targum zu Wajikra 23:42

In tabernacles of two sides according to their rule, and the third a handbreadth (higher), that its shaded part may be greater than that into which cometh the sunshine; to be made for a bower (or shade) for the feast, from different kinds (of materials) which spring from the earth and are uprooted: in measure seven palms, but the height within ten palms. In it you shall sit seven days; the males in Israel, and children who need not their mothers, shall sit in the tabernacles, blessing their Creator whenever they enter thereinto.
