Israel's departure from Sinai - Numbers 10:11-13

It has been two years since Israel left Egypt. Having received
God's travel instructions through Moses, Israel set out from Mount
Sinai into the Desert of Paran on their way toward the promised
land. 

-- Numbers 10:11-13
11 On the twentieth day of the second month of the second year, the cloud lifted from above the tabernacle of the Testimony.
12 Then the Israelites set out from the Desert of Sinai and traveled from place to place until the cloud came to rest in the Desert of Paran.
13 They set out, this first time, at the LORD’s command through Moses.
