יֶאֱרֹ֬ב בַּמִּסְתָּ֨ר ׀ כְּאַרְיֵ֬ה בְסֻכֹּ֗ה יֶ֭אֱרֹב לַחֲט֣וֹף עָנִ֑י יַחְטֹ֥ף עָ֝נִ֗י בְּמָשְׁכ֥וֹ בְרִשְׁתּֽוֹ׃
He lieth in wait in a secret place as a lion in his lair, He lieth in wait to catch the poor; He doth catch the poor, when he draweth him up in his net.
Read halakhic rulings (Jewish law) on Psalms 10:9: and classical halakhic sources.
