Send thee help - Margin, thy help. So the Hebrew. The idea is, such help as he needed; such as would make him safe.
From the sanctuary - From the tabernacle, or the holy place where God was worshipped, and where he was supposed to reside, Exodus 28:43; Exodus 29:30; Exodus 35:19; Exodus 39:1. This was his seat; his throne; where he abode among the people. Here, too, it would seem that he had been worshipped, and his aid implored, in view of this expedition; here the royal psalmist had sought to secure the divine favor by the presentation of appropriate sacrifices and offerings Psalms 20:3. The prayer here is, that God would accept those offerings, and hear those supplications, and would now send the desired help from the sanctuary where he resided; that is, that he would grant his protection and aid.
And strengthen thee - Margin, as in Hebrew, support thee. The idea is, that he would grant his upholding hand in the day of peril.
Out of Zion - The place where God was worshipped; the place where the tabernacle was reared. See the note at Psalms 2:6.
