רָאִ֡תָה כִּֽי־אַתָּ֤ה ׀ עָ֘מָ֤ל וָכַ֨עַס ׀ תַּבִּיט֮ לָתֵ֪ת בְּיָ֫דֶ֥ךָ עָ֭לֶיךָ יַעֲזֹ֣ב חֵלֶ֑כָה יָ֝ת֗וֹם אַתָּ֤ה ׀ הָיִ֬יתָ עוֹזֵֽר׃
Thou hast seen; for Thou beholdest trouble and vexation, to requite them with Thy hand; Unto Thee the helpless committeth himself; Thou hast been the helper of the fatherless.
Radak on Psalms
Thou hast seen: – The yodh of the third radical is missing from the form as written. The wicked man says that Thou dost not see; but Thou hast seen all.
Rashi on Psalms
for You So is Your custom, that You look at mischief and provocation.
