Psalms 81:3-4

81:3 Sound the ram’s horn on the day of the new moon, ¹ 

and on the day of the full moon when our festival begins. ² 

81:4 For observing the festival is a requirement for Israel; ³ 

it is an ordinance given by the God of Jacob.

[81:3]  ¹ tn Heb “at the new moon.”

[81:3]  ² tn Heb “at the full moon on the day of our festival.” The Hebrew word כֶּסֶה (keseh) is an alternate spelling of כֶּסֶא (kese’, “full moon”).
