qw stands for 'Quote word'. It usually used to create array. Ex. @arr = qw/one two three/; This will create an array with elements one, two and three. Instead of '/' symbol, any other symbol can be used. Ex. @arr = qw #one two three#; @arr = qw %one two three%; If using brackets as symbol, we have the option to use open and closing braces on either end. Ex. @arr = qw [one two three]; or, @arr = qw{one two three}; or, @arr = qw (one two three); Note: Each space considered as seperator for new element.
One of them, qawa [hw'q], may denote hope in the sense of trust,  as when Jeremiah addresses God, Our hope is in you ( Jer 14:22 ). He also uses a noun formed from the root qwh [hw'q] to teach that the Lord is the hope of Israel (14:8; 17:13; 50:7), which means that Israel's God is worthy of trust. Another noun from the same root, tiqwa [hw.qiT], is often also translated hope meaning trust..
