Deuteronomy 6:9

6:9 Inscribe them on the doorframes of your houses and gates. ¹ 

[6:9]  ¹ sn The Hebrew term מְזוּזֹת (mÿzuzot) refers both to the door frames and to small cases attached on them containing scripture texts (always Deut 6:4-9 and 11:13-21; and sometimes the decalogue; Exod 13:1-10, 11-16; and Num 10:35-36). See J. H. Tigay, Deuteronomy (JPSTC), 443-44.
