I have laboured # 21_ECC_02_19 # And who knoweth whether he shall be a wise [man] or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have showed myself wise under the sun. This [is] also vanity. 
I have laboured # 23_ISA_49_04 # Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: [yet] surely my judgment [is] with the LORD, and my work with my God.
