Exodus 33:9-10

33:9 And ¹  whenever Moses entered the tent, the pillar of cloud would descend and stand at the entrance of the tent, and the Lord ²  would speak with Moses. ³  33:10 When all the people would see the pillar of cloud standing at the entrance of the tent, all the people, each one at the entrance of his own tent, would rise and worship. ⁴ 

[33:9]  ¹ tn Heb “and it was when.”

[33:9]  ² tn Heb “and he”; the referent (the Lord) has been specified in the translation for clarity.

[33:9]  ³ tn Both verbs, “stand” and “speak,” are perfect tenses with vav (ו) consecutive.

[33:10]  ⁴ tn All the main verbs in this verse are perfect tenses continuing the customary sequence (see GKC 337 §112.kk). The idea is that the people would get up (rise) when the cloud was there and then worship, meaning in part bow down. When the cloud was not there, there was access to seek God.
