A time to get, and a time to lose; a time to keep, and a time to cast away; A time to get - e.g., to gain honestly a livelihood (Ephesians 4:28); Hebrew, seek.
Lose - when God wills losses to us, then is our time to be content.
Keep - not to give to the idle beggar (2 Thessalonians 3:10).
A time to cut away - in charity (Proverbs 11:24), or to part with the dearest object rather than the soul (Mark 9:43). To be careful is right in its place, but not when it comes between us and Jesus Christ (Luke 10:40-42). Hengstenberg explains "seek" of God's retributive righteousness in seeking His persecuted people (Ecclesiastes 3:15), and "cast away," His casting His sinning people from His presence (2 Kings 13:23; 2 Kings 17:18-20; Psalms 71:9; Deuteronomy 29:28; the general context).
