Enlarge the place of thy tent (comp. Isaiah 33:20 and Jeremiah 10:20). The memory of the old nomadic life caused the "tent" to be the symbol and representative of the dwelling-place. Israel will have so many more children that her "tent" will need enlarging.
The curtains; i.e. the tent-cloth (comp. Exodus 26:1-37 and Exodus 36:1-38; where the word used occurs repeatedly). Thy cords … thy stakes (comp. Exodus 35:18; Exodus 39:40, etc.). The ropes and tent-pegs, which kept the tent-cloth in place, are intended.
The enlargement of the tent would make longer ropes and larger pegs necessary.
