Psalm 17:8

New English Translation

⁸Protect me as you would protect the pupil of your eye.^[a]
Hide me in the shadow of your wings.^[b]

Psalm 17:8 tc Heb “Protect me like the pupil, a daughter of an eye.” The noun בַּת (bat, “daughter”) should probably be emended to בָּבַת (bavat, “pupil”). See Zech 2:12 HT (2:8 ET) and HALOT 107 s.v. *בָּבָה.
Psalm 17:8 sn Your wings. The metaphor compares God to a protective mother bird.

Psalm 91:4

New English Translation

⁴He will shelter you^[a] with his wings;^[b]
you will find safety under his wings.
His faithfulness is like a shield or a protective wall.^[c]

Psalm 91:4 tn Heb “put a cover over you” (see Ps 5:11).
Psalm 91:4 tc The Hebrew text has the singular, but the plural should be read. The final י (yod) of the suffix, which indicates the plural, has dropped off by haplography (note the yod at the beginning of the next word).
Psalm 91:4 tn Traditionally the Hebrew term סֹחֵרָה (sokherah), which occurs only here in the OT, has been understood to refer to a buckler or small shield (see BDB 695 s.v.). But HALOT 750 s.v., on the basis of evidence from the cognate languages, proposes the meaning “wall.”
