Albert Barnes Commentary Psalms 20:2

"Send thee help from the sanctuary, And strengthen thee out of Zion;" — Psalms 20:2 (ASV)

Send you help - Margin, your 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 dwelt 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, hear those supplications, and now send the desired help from the sanctuary where he resided; that is, that he would grant his protection and aid.

And strengthen you - Margin, as in Hebrew, support you. 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 erected. See the note at (Psalms 2:6).
