Exodus 1:12-14

Young's Literal Translation

¹² and as they afflict it, so it multiplieth, and so it breaketh forth, and they are vexed because of the sons of Israel;

¹³ and the Egyptians cause the sons of Israel to serve with rigour,

¹⁴ and make their lives bitter in hard service, in clay, and in brick, and in every [kind] of service in the field; all their service in which they have served [is] with rigour.
